Driver’s Log Books and Hours of Service (HOS) Records

The Federal Motor Carrier Safety Administration (FMCSA) mandates strict hours of service for commercial truck drivers to prevent fatigue-related accidents. The driver’s log books and electronic logging devices (ELDs) are invaluable in establishing whether the driver complied with these regulations at the time of the accident. Discrepancies or violations in these records can be a significant indicator of fault.

Truck Maintenance Records

Regular maintenance and inspection of commercial trucks are required by law. Maintenance records can reveal if the trucking company neglected its duty to maintain the vehicle in a safe operating condition, contributing to the accident. Evidence of skipped inspections, deferred maintenance, or repairs can directly impact the determination of fault.

Event Data Recorders (EDR) or “Black Box” Data

Many commercial trucks are equipped with event data recorders, similar to an airplane’s black box, which capture data such as speed, braking, and steering moments before a collision. This data can provide an objective account of the truck’s actions leading up to the accident, offering critical insights into the cause and assigning fault.

Cargo Load and Securement Records

Improper loading or securement of cargo can lead to accidents through shifting loads or spills. Cargo load and securement records can prove whether the cargo was loaded and secured according to industry standards, which can be a pivotal factor in accident causation and liability.

Dash Cam Footage and Surveillance Videos

Visual evidence from dash cams, surveillance cameras near the accident site, or even bystander videos can provide a real-time account of the accident. This footage can be instrumental in reconstructing the accident scene and establishing fault.

Witness Statements

Eyewitness accounts from other motorists, pedestrians, or nearby residents can offer valuable perspectives on the accident. Their testimonies can corroborate other evidence or provide new insights into the events leading up to and during the collision.

Police and Accident Reports

The responding law enforcement officers compile accident reports that include their observations, diagrams of the accident scene, and sometimes preliminary assessments of fault. These reports can be foundational in building a case, though they are not the final word on liability.

Toxicology Reports

If there is suspicion of impairment, toxicology reports from the truck driver can be critical. Evidence of alcohol or drug use at the time of the accident can significantly influence the determination of fault.

Compliance with Federal and State Trucking Regulations

Evidence of compliance or violation of federal and state trucking regulations can be a decisive factor in establishing fault. This includes adherence to weight limits, hazardous material regulations, and vehicle safety standards.

Expert Testimonies

Experts in accident reconstruction, trucking regulations, medical experts, and others can provide authoritative testimonies based on the evidence gathered. Their insights can help clarify complex technical details and strengthen the case.
