Rear-End Collision Claims: Who Is at Fault?

Last reviewed June 2026

Quick answer. In most rear-end collisions the driver who hit you from behind is presumed at fault, because drivers must keep a safe following distance and stay alert. The presumption can be rebutted, for example if you reversed suddenly or had no working brake lights, but the rear driver carries the burden.

Why the Rear Driver Is Usually at Fault

Every driver has a duty to leave enough room to stop safely. When someone strikes you from behind, the law in every Northeast state treats that as strong evidence they were following too closely or not paying attention. That presumption is what makes rear-end claims among the more straightforward to establish.

The Exceptions

You reversed unexpectedly into the other car.
Your brake lights were out, so the driver behind had no warning.
You cut in and stopped abruptly with no room.
A chain reaction pushed one car into another.

In a comparative-fault state, an exception rarely erases the claim. It usually just shifts a percentage of fault, which reduces rather than eliminates recovery. See how that works in our partly-at-fault guide.

What to Do

Photograph both vehicles and the road, get the police report, and see a doctor even if you feel fine, since whiplash and soft-tissue injuries often surface a day or two later.

Frequently Asked Questions

Is the Rear Driver Always at Fault?

Not always, but they are presumed at fault unless they can show an exception applies, such as your sudden reverse or missing brake lights.

The Other Driver Blamed Me for Stopping Short. Now What?

Stopping for traffic, a light, or a hazard is generally lawful, and the following driver is still expected to leave room. Document the scene and the reason you stopped.
