Rear-End Truck Accidents: When a Semi Can't Stop in Time
A loaded tractor-trailer traveling 65 mph needs roughly 525 feet to stop — nearly two football fields, and about 40% more than a passenger car. When a truck driver follows too closely, drives distracted, or hauls with worn brakes, the vehicle in front absorbs a highway-speed impact from 80,000 pounds of steel. Rear-end truck crashes produce some of the clearest liability cases in personal injury law, but insurers still fight them hard.
Why Trucks Rear-End Cars
Leading causes include following too closely (a violation of FMCSA safe-driving rules), distracted driving — texting while driving a CMV is federally banned under 49 CFR §392.80 — fatigue and Hours of Service violations, brake defects and out-of-adjustment brakes (the most common violation in roadside inspections), and speeding in work zones or congested traffic.
Modern trucks increasingly carry forward collision warning and automatic emergency braking. Whether those systems were installed, functioning, or ignored is a growing area of litigation, and event data from these systems can prove exactly what the driver did in the final seconds.
The Evidence That Wins Rear-End Truck Cases
The truck's ECM records speed, throttle, brake application, and hard-braking events. Dash cameras — now common in fleets — capture the approach. ELD records establish how long the driver had been on duty. Cell phone records can prove distraction. Post-crash drug and alcohol testing is federally mandated after qualifying crashes.
This evidence can be overwritten or 'lost' within days if not preserved. A truck accident attorney sends an immediate spoliation letter compelling the carrier to preserve everything, then follows with subpoenas and discovery.
Common Injuries and Compensation
Even 'moderate' rear-end truck impacts cause whiplash, disc herniation, and concussion; severe ones cause TBI, spinal cord injury, and death. Insurers often argue pre-existing conditions or minimize soft-tissue injuries — medical documentation from day one is essential.
Recoverable damages include all medical care (past and future), lost income and earning capacity, vehicle and property loss, and pain and suffering. Where the carrier's brake maintenance program was neglected, punitive damages may be available.
Frequently Asked Questions
The truck driver got a ticket. Does that guarantee I win?
A citation helps but doesn't end the case. Insurers still dispute injury causation and damages. The citation, combined with ECM data and witness testimony, builds a liability picture that supports full-value settlement negotiations.
What if a truck rear-ended me and pushed me into another car?
Chain-reaction crashes are common with trucks. The truck's insurer is typically liable for all impacts its negligence caused, including your liability exposure to the car ahead. An attorney coordinates these claims so you aren't caught in the middle.
I was rear-ended by a delivery box truck, not a semi. Same rules?
Largely yes — commercial vehicles and their operators owe heightened duties, and companies are vicariously liable for their drivers. Delivery fleet claims (Amazon DSPs, FedEx, UPS) add contractor-relationship questions an experienced lawyer knows how to navigate.
