Rear-End Truck Accidents
When a truck rear-ends a car, the truck driver is usually at fault for following too closely, speeding or being distracted. A loaded truck needs far more distance to stop than a car, so drivers must leave extra space. Federal rules also ban truck drivers from texting or using a handheld phone while driving.
Why are rear-end crashes with trucks so serious?
A loaded tractor-trailer can weigh up to 80,000 pounds, many times more than a passenger car. Even at moderate speed, that force can push a car into the vehicle ahead or off the road, causing spinal, head and multiple-impact injuries.
What rules apply to truck drivers' following and distraction?
Several federal rules are relevant to rear-end crashes:
- Commercial drivers may not text while driving (49 CFR 392.80) or use a handheld mobile phone (49 CFR 392.82).
- Drivers must not drive while impaired by fatigue or illness (49 CFR 392.3).
- Hours-of-service limits restrict driving time to reduce fatigue (49 CFR 395.3).
What if a car rear-ends a truck?
The following driver is often presumed at fault, but not always. If the truck stopped suddenly without reason, was parked illegally, had no working lights or reflectors, or had a defective rear guard, the truck driver or carrier may share or carry the blame. See our guide to underride accidents.
Frequently asked questions
Who is at fault when a truck rear-ends a car?
Usually the truck driver, because drivers must keep a safe following distance for their speed and load. The carrier can also be liable for pushing unrealistic schedules or poor brake maintenance.
How much longer does a truck need to stop?
A loaded truck needs substantially more distance to stop than a car at the same speed, because of its weight and air-brake lag. That is why following too closely is a common factor in truck rear-end crashes.
Can truck drivers use their phone while driving?
No. Federal rules ban commercial drivers from texting (49 CFR 392.80) and from using a handheld mobile phone (49 CFR 392.82) while driving.
What evidence proves a truck was following too closely?
Engine control module data showing speed and braking, forward-facing dashcam footage, ELD records, phone records and witness statements. Many trucks also have collision-warning systems that log alerts.
I was rear-ended by a truck and my neck hurts days later. Can I still claim?
Yes. Neck and back symptoms often appear after a delay. See a doctor promptly so the injury is documented and linked to the crash.
