How Are Truck Accidents Different Than Car Accidents?

by / ⠀Blog / July 31, 2025
Truck accidents differ from car accidents in several key ways, primarily due to the size, weight, and design of commercial trucks. The significant size and weight of trucks usually result in more severe damage and complex liability issues compared to car accidents. This makes understanding their differences crucial for anyone involved in a collision. The nature of trucking regulations, such as hours-of-service rules and mandatory inspections, also sets truck accidents apart. These factors influence how accidents are investigated and handled legally. 

Key Differences Between Truck Accidents and Car Accidents

Truck accidents differ from car accidents due to factors such as vehicle size, injury severity, and specific regulations governing trucks. 

Size and Weight Disparities

Trucks are significantly larger and heavier than cars, often weighing 20 to 30 times more. This weight difference affects how trucks impact smaller vehicles during collisions. For example, a fully loaded tractor-trailer can weigh up to 80,000 pounds, compared to an average car weight of 4,000 pounds. The size disparity also means trucks require longer distances to stop, increasing collision risks in sudden braking situations. Furthermore, trucks have larger blind spots, making it harder for drivers to see nearby cars, which contributes to accidents.

Severity of Injuries and Damages

Due to the massive size and weight of trucks, accidents involving them usually result in more severe injuries and greater property damage. Injuries often include traumatic brain injuries, spinal cord damage, and multiple fractures. Cars involved in truck collisions frequently sustain major structural damage, leading to higher medical and repair costs. Fatalities are also more common in these crashes compared to typical car-only accidents. The force exerted in these crashes is much greater, increasing the likelihood of life-threatening outcomes.

Regulatory Differences

Trucks must comply with stricter federal and state regulations than passenger cars. These rules cover hours of service for drivers, vehicle maintenance requirements, and load limits, all designed to promote safety on the road. Commercial truck drivers must also undergo mandatory training and regular medical examinations. Unlike car drivers, truck drivers are subject to drug and alcohol testing by their employers. These regulatory factors impact liability and insurance claims in truck accident cases.

Causes and Contributing Factors

Truck accidents often involve unique factors related to the size and operation of commercial vehicles. These factors affect how accidents happen and how liability is assessed in ways that differ from typical car accidents.

Driver Fatigue and Training

Truck drivers face strict federal hours-of-service regulations designed to prevent fatigue. Despite this, long routes and tight deadlines can lead to drowsy driving. Training for truck drivers is more rigorous than for car drivers, requiring specialized knowledge of handling large vehicles under different conditions. However, gaps in training or failure to follow protocols increase accident risks. Fatigue reduces reaction time and decision-making ability. Combined with complex vehicle controls, this makes driver exhaustion a primary cause in many truck-related crashes.

Vehicle Maintenance Requirements

Commercial trucks are subject to strict maintenance standards imposed by the Federal Motor Carrier Safety Administration (FMCSA). Regular inspections focus on brakes, tires, lights, and suspension systems. Failure to maintain these components properly can cause mechanical failures, leading to accidents. For example, brake malfunctions are more dangerous due to the truck’s weight and momentum.

Legal and Liability Challenges

Truck accidents involve more complicated legal and liability issues than typical car accidents. Different parties may share fault, while evidence requires careful handling to support claims. 

Multiple Liable Parties

Truck accidents often include several liable parties, such as the truck driver, trucking company, vehicle manufacturer, and sometimes third-party contractors. Each party’s level of responsibility must be established, which can require detailed investigation into employment records, maintenance logs, and driver qualifications. Washington State law allows claims against any or all responsible parties, but proving liability needs careful legal strategy. A Truck Accident Lawyer in Washington State is crucial to identify every potential defendant and ensure proper claims. Insurance companies for trucking firms usually have larger policies, increasing the stakes.

Evidence Collection and Preservation

Evidence in truck accidents must be collected promptly and preserved meticulously. Key items include the truck’s electronic logging device (ELD), black box data, inspection reports, and eyewitness statements. The complexity of commercial trucking rules means laws often set strict deadlines for securing evidence. Failure to preserve data from electronic devices or maintenance documents can weaken a case severely. A Truck Accident Attorney in Washington State typically works quickly to get court orders for evidence preservation. Additionally, physical evidence like skid marks and vehicle damage requires professional analysis. Photo by Robson Hatsukami Morgan; Unsplash
