When a semi truck crash happens, the devastating impact extends far beyond the immediate scene. With approximately 494,000 crashes involving large trucks reported annually in the United States, these incidents represent one of the most significant public safety challenges on our highways. The sheer size and weight of these vehicles—often 20 to 30 times heavier than passenger cars—means that when accidents occur, the consequences are severe and far-reaching.
Recent data reveals that roughly 5,700 of these crashes result in fatalities each year, while around 110,000 cause injuries. Perhaps most sobering is that nearly one in four semi truck crashes involves either an injury or fatality, highlighting the critical importance of understanding what causes these accidents and how they can be prevented.
This comprehensive guide examines the complex factors behind semi truck crashes, from driver fatigue and mechanical failures to weather conditions and infrastructure challenges. We’ll also analyze a recent major incident that occurred in Grand Rapids, Michigan, which serves as a stark reminder of how a single crash can impact entire communities for years to come.
Common Causes of Semi Truck Crashes
Understanding the root causes behind semi truck crashes is essential for developing effective prevention strategies. Research from the Federal Motor Carrier Safety Administration’s landmark Large Truck Crash Causation Study reveals clear patterns in how and why these accidents occur.
Driver Fatigue and Hours of Service Violations
Driver fatigue emerges as the leading cause of semi truck crashes, contributing to approximately 87% of all truck-related accidents. The demanding nature of the trucking profession, with long hours on the road and pressure to meet tight delivery schedules, creates dangerous conditions where exhausted drivers struggle to maintain safe operation of their vehicles.
Despite federal hours-of-service regulations designed to prevent fatigue-related crashes, violations remain common. The pressure to maximize income and meet delivery deadlines often conflicts with safety requirements, leading some drivers to falsify logbooks or push beyond safe limits. When driver fatigue sets in, reaction times slow dramatically, and the ability to make split-second decisions that could prevent a crash becomes severely compromised.
Mechanical Failures Including Brake Malfunctions and Tire Blowouts
Vehicle mechanical problems account for approximately 10% of semi truck crashes. The most critical failures involve braking systems, which must handle the enormous weight and momentum of fully loaded trucks. When brakes fail or become overheated on long downhill grades, drivers lose the ability to control their speed or stop safely.
Tire blowouts represent another significant mechanical cause of crashes. The tremendous weight carried by semi trucks puts immense stress on tires, and when they fail at highway speeds, the resulting loss of control can be catastrophic. Poor maintenance schedules, inadequate inspections, and the pressure to minimize downtime all contribute to increased mechanical failure rates.
Overloaded or Improperly Secured Cargo Exceeding Weight Limits
Cargo-related issues create multiple crash risks for semi trucks hauling various loads. Overloaded vehicles experience compromised braking performance, increased stopping distances, and greater difficulty navigating turns and curves. The additional weight also places excessive stress on tires, brakes, and suspension components, increasing the likelihood of mechanical failures.
Improperly secured cargo poses an equally serious threat. When loads shift during transit, they can dramatically alter the vehicle’s center of gravity, leading to rollover crashes or jackknife incidents. Load securement violations remain among the most frequently cited safety infractions during commercial vehicle inspections.
Weather-Related Factors Such as Rain, Snow, and High Winds
Environmental conditions account for approximately 3% of truck crashes, but their impact is often underestimated. Rain and snow reduce tire traction and visibility while significantly increasing stopping distances. Semi trucks, due to their size and weight, are particularly vulnerable to these conditions and require much greater following distances than passenger vehicles.
High winds present a unique challenge for trucks hauling large, high-profile trailers. Crosswinds can push vehicles out of their lanes, while sudden gusts can trigger rollover crashes, especially on bridges and in open areas. Many truck crashes occur when drivers fail to adjust their speed and driving behavior to match deteriorating weather conditions.
Distracted Driving and Cell Phone Use While Operating
The proliferation of electronic devices has introduced new distraction hazards for truck drivers. Cell phone use, GPS navigation, electronic logging devices, and onboard computers all compete for driver attention. Even momentary distractions can be deadly when operating a vehicle that may require several hundred feet to come to a complete stop.
The elevated driving position in semi trucks can also create a false sense of security, leading some drivers to engage in risky behaviors they might avoid in passenger vehicles. However, the physics of truck operation mean that any distraction significantly increases crash risk.
Speeding and Failure to Adjust for Road Conditions
Speeding was a contributing factor in 7.3% of deadly truck crashes in 2020. The pressure to meet delivery schedules often encourages drivers to exceed safe speeds, particularly on interstate highways where much of the country’s freight moves. However, the increased kinetic energy of speeding trucks makes crashes exponentially more severe.
Failure to adjust speed for road conditions—whether due to construction zones, heavy traffic, or weather—compounds the speeding problem. Many crashes occur when truck drivers maintain highway speeds in situations that require significant speed reductions.
Types of Semi Truck Accidents
Different types of semi truck crashes present unique challenges and dangers. Understanding these patterns helps identify prevention strategies and highlights the importance of proper training and safety equipment.
Jackknife Accidents Where Trailer Swings Perpendicular to Cab
Jackknife accidents occur when the trailer of a semi truck swings out perpendicular to the cab, resembling the folding motion of a pocket knife. These crashes typically happen during hard braking on slippery surfaces or when the trailer’s wheels lock up while the tractor maintains traction.
The results are often catastrophic, as the out-of-control trailer can sweep across multiple lanes of traffic, striking numerous vehicles. Jackknife accidents frequently block entire highways for hours while cleanup crews work to clear the scene and check for structural damage to road surfaces and barriers.
Rollover Crashes Often Involving High Speeds on Curves
Rollover crashes represent one of the deadliest types of truck accidents, accounting for 50% of truck occupant deaths. These incidents typically occur when trucks take curves or ramps at excessive speeds, causing the high center of gravity to overcome the vehicle’s stability limits.
The weight distribution of the cargo plays a critical role in rollover susceptibility. Liquid loads, improperly secured freight, or top-heavy configurations all increase rollover risk. When a truck flipped in such an accident, the resulting scene often requires specialized heavy-duty recovery equipment and can close highways for extended periods.
Rear-End Collisions Due to Extended Stopping Distances
The physics of semi truck operation create inherent challenges in avoiding rear-end collisions. A fully loaded truck traveling at highway speeds may require 400 feet or more to come to a complete stop—nearly four times the distance needed by a passenger car under similar conditions.
These extended stopping distances mean that truck drivers must maintain much larger following distances and remain constantly vigilant for traffic changes ahead. When traffic suddenly slows or stops, trucks that are following too closely often cannot avoid rear-end collisions, sometimes resulting in multi-vehicle pile-ups.
Side-Impact Crashes at Intersections and Highway Merges
Intersections and highway merge points present particular dangers for semi trucks due to their size and the time required to accelerate or change direction. Side-impact crashes often occur when truck drivers misjudge gaps in traffic or when other vehicles fail to account for the truck’s limited maneuverability.
The extensive blind spots around large trucks contribute significantly to side-impact crashes. Despite multiple mirrors and modern safety technology, substantial areas around trucks remain invisible to drivers, particularly directly alongside the trailer and immediately behind the vehicle.
Underride Accidents Where Vehicles Slide Beneath Trailers
Underride accidents represent some of the most horrific truck crashes, occurring when passenger vehicles slide underneath truck trailers. These incidents are especially lethal because the truck’s trailer often strikes the passenger compartment rather than the vehicle’s designed crush zones.
Federal regulations require rear underride guards on trailers, but these safety devices have limitations and may not prevent all underride scenarios. Side underride protection remains less comprehensive, leaving significant gaps in safety coverage.
Multi-Vehicle Pile-Ups on Highways and Interstates
When semi truck crashes occur on busy highways, they often trigger chain-reaction accidents involving multiple vehicles. The inability of following traffic to stop in time, combined with reduced visibility from weather or debris, creates conditions for massive pile-ups.
These incidents can involve dozens of vehicles and result in numerous casualties. The complexity of multi-vehicle crashes also makes them extremely difficult to investigate and often leads to lengthy highway closures while authorities work to determine the sequence of events.
Recent Major Semi Truck Crash: Grand Rapids Case Study
The April 2024 incident on US 131 near downtown Grand Rapids serves as a compelling case study in how a single semi truck crash can have far-reaching consequences for infrastructure and communities. This accident demonstrates the unique challenges posed by Michigan’s weight regulations and highlights the potential for long-term impacts from truck crashes.
Incident Details and Immediate Response
The crash happened when a semi truck hauling pea gravel and sand, with a total weight of 140,000 pounds, was headed south on US 131. The driver lost control and caused the truck to veer left into a concrete wall near the I-196 interchange. The impact was severe enough that the truck flipped, trapping the driver for about an hour before emergency responders could extract him.
Courtesy Michigan State Police and other emergency services responded quickly to the scene, working to free the trapped driver and assess the extent of the damage. Remarkably, the driver sustained only minor injuries despite being trapped in the wreckage for an extended period. No other vehicles were involved in the crash, preventing what could have been a much more devastating incident.
The accident initially blocked the left lanes of southbound US 131, creating snarled traffic throughout the Grand Rapids area. Emergency crews worked to stabilize the scene and begin the complex process of removing the overturned truck and its scattered cargo of pea gravel and sand.
Infrastructure Damage and Long-Term Closure
What made this crash particularly significant was not just the immediate impact, but the long-term structural concerns it raised. The force of a 140,000-pound truck hitting the concrete wall and barrier system raised serious questions about the integrity of the highway infrastructure in that area.
Engineers determined that a full structural inspection of the affected ramp and surrounding infrastructure would be necessary before traffic could safely resume normal patterns. This decision led to an unprecedented closure—the ramp coming from westbound I-196 to southbound US 131 was closed indefinitely, with repairs expected to continue until April 2026.
The two-year closure timeline reflects the complex engineering challenges involved in assessing and repairing infrastructure damaged by such massive forces. The concrete wall and supporting structures required detailed analysis to ensure they could safely handle future traffic loads.
Michigan’s Unique Weight Regulations
This incident highlighted Michigan’s distinctive approach to truck weight limits. While most states limit truck weights to 80,000 pounds, Michigan allows trucks to operate at weights up to 164,000 pounds under specific conditions. This policy is designed to support the state’s manufacturing and agricultural sectors but creates unique safety and infrastructure challenges.
The 140,000-pound truck involved in this crash was operating legally under Michigan law, but the accident demonstrated the potential consequences when such heavy vehicles lose control. The additional weight significantly increases the destructive force in any collision and places greater demands on highway infrastructure.
State transportation officials have had to design and maintain roads capable of handling these heavier loads while ensuring adequate safety margins for accident scenarios. This incident prompted renewed discussions about the balance between economic benefits and safety considerations in truck weight regulations.
Emergency Response and Cleanup Operations
The cleanup operation following this crash illustrated the complexity of dealing with heavy truck accidents. Specialized heavy-duty recovery equipment was required to right the overturned truck and remove it from the scene. The spilled cargo of pea gravel and sand had to be collected and properly disposed of or recycled.
Emergency response teams had to coordinate multiple aspects of the cleanup while maintaining safety for both workers and passing traffic. The process involved not only removing the damaged truck but also cleaning up any diesel fuel spill and ensuring that the roadway surface was safe for traffic once the immediate debris was cleared.
The hours-long closure of major traffic arteries during rush periods created significant economic impacts for the community. Commuters, freight carriers, and local businesses all felt the effects of the disrupted traffic patterns, demonstrating how a single truck crash can have ripple effects throughout a region.
Infrastructure and Economic Impact
The consequences of semi truck crashes extend far beyond the immediate scene, creating substantial infrastructure damage and economic disruption that can persist for months or even years. Understanding these broader impacts helps illustrate why prevention efforts are so critical for maintaining efficient transportation systems.
Highway Closures and Traffic Delays
When a semi truck crash occurs on a major highway, the resulting traffic disruptions can affect thousands of commuters and freight movements. The Grand Rapids incident, which remained a source of traffic delays for hours Tuesday and beyond, demonstrates how a single accident can create cascading effects throughout a transportation network.
Highway closures following truck crashes often last much longer than those from passenger car accidents. The size and weight of commercial vehicles require specialized recovery equipment, and the potential for hazardous cargo spills adds complexity to cleanup operations. During these closures, traffic must be rerouted through local roads not designed to handle such volumes, creating additional congestion and safety concerns.
The economic cost of these delays extends beyond mere inconvenience. Freight shipments may be delayed, affecting supply chains and potentially leading to production disruptions. Emergency vehicles may face longer response times when forced to navigate around closed highways, and fuel consumption increases as vehicles idle in traffic or take longer routes.
Structural Damage Requiring Extensive Inspections
The force generated when a loaded semi truck strikes highway infrastructure can cause significant structural damage that may not be immediately apparent. Concrete barriers, bridge supports, overpasses, and road surfaces all face stresses far beyond their normal design parameters during serious truck crashes.
Following the Grand Rapids incident, engineers determined that comprehensive structural inspections were necessary to ensure the continued safety of the affected infrastructure. This process requires specialized equipment and expertise to assess potential damage to foundations, reinforcing steel, and other critical components.
The decision to close the ramp indefinitely until April 2026 reflects the conservative approach necessary when dealing with potentially compromised infrastructure. The costs associated with these inspections and any necessary repairs can reach millions of dollars, expenses ultimately borne by taxpayers and transportation agencies.
Environmental Concerns from Fuel Spills and Cargo Contamination
Semi trucks typically carry 200-300 gallons of diesel fuel, and when a crash occurs, the potential for environmental contamination becomes a serious concern. Diesel fuel spills can contaminate soil and groundwater, requiring expensive remediation efforts and potentially affecting local water supplies.
Beyond fuel spills, the cargo carried by trucks can create additional environmental hazards. Chemical loads, agricultural products, and even seemingly benign materials like pea gravel can present cleanup challenges and potential contamination risks depending on the accident circumstances.
Environmental response teams must often be called to assess and mitigate these risks, adding to both the duration of highway closures and the overall cost of accident response. The cleanup process must meet strict environmental standards, which can significantly extend the time required to fully reopen affected roadways.
Economic Losses from Delayed Freight Deliveries
The trucking industry moves approximately 70% of all freight in the United States, making highway closures and traffic delays particularly costly for the economy. When major routes are blocked or significantly slowed due to truck crashes, the ripple effects extend throughout supply chains.
Perishable goods may spoil during extended delays, leading to direct financial losses for shippers and receivers. Manufacturing operations dependent on just-in-time delivery schedules may experience production disruptions when critical components fail to arrive as expected.
The costs extend to the trucking industry itself, where drivers may exceed allowable hours due to unexpected delays, requiring them to take mandatory rest breaks that further disrupt delivery schedules. Fleet operators must often reroute other vehicles to avoid closed highways, increasing fuel costs and driver hours.
Emergency Response Costs for Rescue and Cleanup Operations
The complexity of responding to semi truck crashes requires significant emergency service resources. Fire departments, police agencies, emergency medical services, and specialized heavy recovery teams all must coordinate their efforts to manage the scene safely and effectively.
The specialized equipment required for truck accident response represents a substantial investment for emergency services. Heavy-duty towing and recovery equipment, hazardous materials response capabilities, and traffic management resources all come at significant cost to local communities.
These costs are often not fully recovered through insurance claims or traffic fines, meaning that taxpayers ultimately bear much of the expense associated with truck crash response. This economic reality provides additional motivation for investing in prevention programs and safety technologies that can reduce crash frequency and severity.
Legal Consequences and Liability
The legal ramifications of semi truck crashes involve multiple layers of investigation, regulation, and potential liability. These cases often prove more complex than typical motor vehicle accidents due to federal regulations, commercial insurance requirements, and the severe consequences that frequently result from truck crashes.
Federal Motor Carrier Safety Administration Investigations
When a serious semi truck crash occurs, the Federal Motor Carrier Safety Administration (FMCSA) typically launches a comprehensive investigation to determine contributing factors and potential regulatory violations. These investigations examine driver records, vehicle maintenance histories, company safety practices, and compliance with federal regulations.
FMCSA investigators have broad authority to review electronic logging device records, driver qualification files, and company safety management systems. The investigation process can take months or even years to complete, particularly in complex cases involving multiple vehicles or serious injuries.
The findings from these investigations can result in civil penalties, safety improvement orders, or even the suspension of a company’s operating authority. Patterns of violations or serious safety deficiencies can lead to increased oversight and monitoring of trucking operations.
Potential Criminal Charges for Violations of Safety Regulations
In cases where truck crashes result from serious regulatory violations or criminal conduct, drivers and trucking companies may face criminal charges. These can include vehicular homicide or manslaughter charges when driver negligence or reckless behavior contributes to fatal accidents.
Hours-of-service violations, driving under the influence, or operating vehicles with known safety defects can all lead to criminal liability. The pressure to meet delivery schedules that leads to regulatory violations may also result in conspiracy charges against company management who encourage or facilitate such violations.
Criminal cases involving truck crashes often receive significant attention from prosecutors due to the serious nature of the injuries and fatalities that frequently result. The enhanced penalties available under commercial vehicle statutes reflect society’s recognition of the special responsibility that comes with operating large trucks on public highways.
Civil Liability for Property Damage and Personal Injuries
The civil liability exposure in truck crash cases often reaches millions of dollars due to the severe injuries and extensive property damage that typically result from these accidents. In fatal crashes, 96% of occupants in passenger vehicles involved in two-vehicle crashes with trucks are killed, highlighting the devastating nature of these collisions.
Trucking companies face liability under multiple legal theories, including direct negligence in hiring, training, and supervision of drivers, as well as vicarious liability for driver actions. The federal requirement for minimum insurance coverage of $750,000 to $5 million depending on cargo type provides a baseline for compensation, but damages often exceed these amounts.
Personal injury attorneys increasingly focus on truck crash cases due to the potential for substantial settlements and verdicts. While verdicts under $1 million are more common than “nuclear verdicts” over $10 million, the average settlement amounts continue to increase as juries become more willing to hold trucking companies accountable for preventable crashes.
Insurance Claims Often Exceeding Millions of Dollars
The insurance implications of semi truck crashes extend far beyond typical auto accidents. Commercial truck insurance policies must account for the potential for catastrophic losses, leading to higher premiums and more complex coverage arrangements.
Insurance companies employ specialized investigators and adjusters with expertise in truck crash reconstruction and federal regulations. The claims process often involves multiple insurance companies when crashes involve multiple vehicles, and coordination between different insurers can complicate and extend the claims resolution process.
Fewer than 2% of reported insurance claims result in litigation, indicating that most cases are resolved through negotiated settlements. However, the complexity of determining fault and calculating damages in truck cases means that settlement negotiations often take significantly longer than typical auto accident claims.
Company Safety Ratings and Operating Authority Implications
Truck crashes can have severe implications for a company’s ability to continue operating. The FMCSA uses crash data as a key component in determining motor carrier safety ratings, which affect a company’s ability to obtain insurance, secure freight contracts, and maintain operating authority.
Companies with poor safety ratings may face increased regulatory oversight, mandatory safety audits, and restrictions on their operations. In severe cases, companies may lose their operating authority entirely, effectively ending their ability to operate as commercial motor carriers.
The reputational impact of serious truck crashes can also affect a company’s relationships with customers and insurance providers. Many large shippers now require their carriers to maintain specific safety ratings and may terminate relationships with companies involved in preventable crashes.
Prevention and Safety Measures
Preventing semi truck crashes requires a comprehensive approach involving enhanced training, technology implementation, regulatory enforcement, and infrastructure improvements. The multifaceted nature of crash causation demands equally diverse prevention strategies.
Enhanced Driver Training Programs and Certification Requirements
The foundation of truck crash prevention lies in ensuring that drivers possess the skills and knowledge necessary to safely operate these complex vehicles. Current entry-level driver training requirements mandate a minimum of 240 hours of instruction, including both classroom and behind-the-wheel training.
However, many safety experts advocate for even more extensive training programs that better prepare drivers for the real-world challenges they will face. Advanced training should include specialized instruction on managing cargo weight distribution, recognizing and responding to mechanical problems, and operating safely in various weather conditions.
Ongoing professional development and refresher training can help experienced drivers maintain and improve their skills throughout their careers. Many progressive trucking companies now implement comprehensive safety programs that go beyond minimum regulatory requirements to address specific crash risks identified in their operations.
Electronic Logging Devices to Monitor Hours of Service Compliance
The implementation of electronic logging devices (ELDs) has significantly improved compliance with federal hours-of-service regulations. These devices automatically record driving time and make it much more difficult for drivers to falsify logbooks or exceed allowable driving hours.
ELD data has proven valuable not only for regulatory compliance but also for crash investigation and analysis. When accidents occur, investigators can quickly access accurate records of driver hours and duty status, helping to determine whether fatigue played a role in the crash.
The technology continues to evolve, with newer systems offering additional safety features such as real-time monitoring of driver behavior, automatic alerts for potential violations, and integration with fleet management systems that help optimize schedules while maintaining safety compliance.
Regular Vehicle Inspections and Maintenance Schedules
Preventing mechanical failures requires rigorous attention to vehicle maintenance and inspection procedures. Federal regulations mandate daily pre-trip inspections by drivers, periodic inspections by qualified mechanics, and annual comprehensive inspections for all commercial vehicles.
However, the pressure to maximize vehicle utilization sometimes conflicts with optimal maintenance practices. Progressive fleet operators have implemented predictive maintenance programs that use vehicle data to identify potential problems before they result in roadside breakdowns or safety hazards.
The development of connected vehicle technology allows for real-time monitoring of critical systems such as brakes, tires, and engine performance. These systems can alert drivers and fleet managers to developing problems and help schedule maintenance during planned downtime rather than waiting for component failures.
Weight Limit Enforcement and Proper Cargo Distribution
Effective weight limit enforcement requires both roadside inspection capabilities and sophisticated weighing systems that can identify overweight vehicles without disrupting traffic flow. Weigh-in-motion technology allows enforcement officers to screen trucks while they maintain highway speeds, targeting only potentially overweight vehicles for detailed inspection.
Proper cargo distribution involves more than simply staying within legal weight limits. Load securement and weight distribution affect vehicle stability, braking performance, and tire wear. Training programs for both drivers and cargo loading personnel help ensure that loads are properly secured and distributed to maintain vehicle safety.
The implementation of electronic weight monitoring systems in trucks can provide real-time feedback to drivers about load distribution and help prevent overloading. These systems can also assist in optimizing fuel efficiency by ensuring that vehicles operate within their most efficient weight ranges.
Advanced Safety Technologies Including Collision Avoidance Systems
Modern truck safety technology includes automatic emergency braking systems, lane departure warnings, blind spot monitoring, and collision avoidance systems. These technologies can help prevent crashes by alerting drivers to dangerous situations or even taking corrective action automatically.
Forward collision warning systems use radar and cameras to detect potential crash situations and alert drivers when immediate action is necessary. Automatic emergency braking can apply the brakes when a collision appears imminent, potentially reducing crash severity even when prevention is not possible.
Lane departure warning and lane keeping assist systems help prevent crashes caused by driver inattention or fatigue. These systems can detect when a vehicle is drifting out of its lane and provide warnings or gentle steering corrections to keep the vehicle in its proper position.
Improved Highway Design and Truck-Specific Infrastructure
Highway infrastructure improvements can significantly reduce truck crash risk and severity. Truck-specific climbing lanes on grades help prevent speed differentials that contribute to crashes, while rumble strips and enhanced curve warning systems alert drivers to potentially dangerous situations.
Improved barrier systems and guardrail designs can better contain errant trucks and prevent crossover crashes into oncoming traffic. The development of high-tension cable median barriers has proven particularly effective at preventing crossover crashes while minimizing maintenance requirements.
Smart highway systems that can provide real-time information about traffic conditions, weather, and potential hazards help drivers make informed decisions about speed and routing. Variable message signs and connected vehicle technology can communicate directly with trucks to provide warnings about dangerous conditions ahead.
The ongoing development of dedicated truck facilities, including improved parking areas and inspection facilities, helps address driver fatigue by providing safe places for mandated rest breaks. These improvements support compliance with hours-of-service regulations while enhancing overall highway safety.
Understanding the complexity of semi truck crashes—from their diverse causes to their far-reaching consequences—underscores the critical importance of comprehensive prevention efforts. The Grand Rapids case study demonstrates how a single incident can affect an entire community for years, while the broader statistics reveal the ongoing challenge these crashes present to public safety.
Effective prevention requires commitment from all stakeholders: drivers must maintain professional standards and comply with safety regulations, trucking companies must invest in proper training and maintenance, regulators must enforce safety requirements consistently, and infrastructure planners must design highways that accommodate the realities of modern freight transportation.
The integration of advanced safety technologies, enhanced training programs, and improved infrastructure design offers hope for reducing both the frequency and severity of semi truck crashes. However, success will ultimately depend on the sustained commitment of the entire transportation industry to prioritize safety over short-term economic pressures.
As freight volumes continue to grow and our highways become increasingly congested, the imperative for preventing truck crashes becomes even more critical. The human and economic costs of these accidents are simply too high to accept as inevitable consequences of our transportation system. Through continued focus on prevention, enforcement, and technological advancement, we can work toward a future where semi truck crashes become increasingly rare events rather than daily occurrences on our nation’s highways.
