Rear-end collisions are among the most common types of car accidents in California, and they come with a legal advantage most people don’t realize: the law generally presumes the driver who hit you from behind is at fault.

The Legal Basis for the Presumption

Under California Vehicle Code section 21703, drivers may not follow another vehicle more closely than is reasonable and prudent, given the speed of travel and the condition of the roadway. Because a rear-end collision is exactly the type of harm this statute is meant to prevent, courts and insurance companies generally treat a violation of the following-distance law as evidence of negligence. In practice, this means the rear driver carries the initial burden of showing they weren’t negligent, rather than the injured front driver having to prove the other driver was at fault.

The Presumption Can Be Rebutted

This presumption is not absolute. A rear driver can present evidence to shift some or all of the fault back to the front driver, including:

  • The front driver stopped suddenly without a legitimate reason
  • The front driver’s brake lights were not working
  • The front driver cut into the lane without enough room to stop safely
  • The front driver reversed unexpectedly

Because California follows a pure comparative negligence system under Li v. Yellow Cab Co., fault doesn’t have to be all-or-nothing. A jury or insurance adjuster can find that both drivers share some responsibility, and compensation is reduced in proportion to each driver’s share of fault.

What This Means If You Were Rear-Ended

If you were hit from behind, the law is generally on your side from the start. That said, insurance companies still look for any evidence that could shift fault back to you, so it’s worth taking a few steps after the crash:

  • Call 911 and get a police report documenting the crash
  • Take photos of both vehicles, the road, and any skid marks
  • Get contact information from any witnesses
  • Seek medical attention, even if you feel fine at first, since injuries like whiplash don’t always show symptoms right away
  • Avoid admitting fault or making recorded statements to the other driver’s insurance company before speaking with an attorney

What If You Were the Rear Driver?

If you were the trailing driver, you’re not automatically out of options. If the front driver’s actions contributed to the crash, an experienced attorney can investigate the evidence and argue for a fairer allocation of fault under California’s comparative negligence rules.
