## Fault in California Rear-End Collisions

California law presumes the **rear driver is negligent** in a rear-end collision. This presumption comes from the legal duty to maintain a safe following distance (Cal. Veh. Code § 21703).

However, this presumption is **rebuttable**. The rear driver may argue:

– The lead driver **stopped suddenly without cause**
– The lead driver’s **brake lights were not working**
– The lead driver **reversed** into the rear vehicle
– The lead driver **cut off** the rear driver
– **Road conditions** (sudden debris, oil spill) caused the collision

### Pure Comparative Negligence Advantage

California’s system is uniquely favorable for rear-end collision victims. Even if you bear some fault, you still recover. If you were rear-ended but the insurer argues you contributed by braking suddenly:

– 10% your fault on $80,000 damages = $72,000 recovery
– 30% your fault on $80,000 damages = $56,000 recovery
– Even 60% your fault = $32,000 recovery

There is **no fault bar** in California — unlike Texas (51%) or Georgia (50%).

## Insurance and Compensation

### Filing Your Claim

– **Lead driver (rear-ended):** File a third-party claim with the rear driver’s insurer
– **Rear driver:** You may still recover if the lead driver contributed — pure comparative negligence protects your claim
– **Do not forget the SR-1** — separate from the police report, required within 10 days

### Minimum Coverage: 30/60/15

As of 2025 (SB 1107), California requires 30/60/15 minimum coverage. Property damage claims up to $15,000 should be covered by the at-fault driver’s minimum policy.

## Frequently Asked Questions

### Is the rear driver always at fault in California?
The rear driver is **presumed** at fault, but this can be overcome with evidence. Even if the rear driver is partly at fault, California’s pure comparative negligence means they can still recover for the other driver’s share of fault.

### Do I need to file an SR-1?
Yes, within 10 days if injury or $1,000+ property damage. This is separate from the police report and failure to file can result in license suspension.

### How long do I have to file a claim?
2 years for personal injury, 3 years for property damage. Only 6 months if a government entity is involved.
