California's pure comparative fault system allows recovery even if you were partly at fault in a rear-end collision. This guide explains how fault is allocated in rear-end cases, how insurers use comparative fault to reduce offers, and how courts apply the Li v. Yellow Cab standard.
California rear-end collision law is anchored by Vehicle Code Section 21703, which creates a rebuttable presumption of fault against the following driver whenever a rear-end collision occurs. This presumption shifts the burden of proof: rather than requiring the rear-end victim to prove the following driver was negligent, the law presumes the following driver violated Section 21703's safe following distance requirement. The following driver must produce evidence to rebut the presumption, typically by showing a sudden, unexpected stop or other emergency.
The eggshell plaintiff rule provides additional protection for rear-end collision victims in California: the at-fault driver must compensate the full extent of injury, even if a pre-existing condition made the victim more susceptible. This rule is especially important in whiplash cases where the insurer argues the cervical injury predated the collision. Consistent medical documentation — beginning with same-day emergency department records — is essential to overcoming the insurer's pre-existing condition defense.
California's pure comparative fault system from Li v. Yellow Cab Co. (1975) allows rear-end collision victims to recover even if they were partly at fault. The victim's damages are reduced proportionally by their fault percentage but not eliminated. When the rear driver has no insurance, the victim's own uninsured motorist coverage under California Insurance Code Section 11580.2 is the primary recovery mechanism.
The statute of limitations for California rear-end collision claims is two years from the date of the accident under CCP Section 335.1. Government entity claims require a written administrative claim within six months under Government Code Section 945.4. California does not cap damages in rear-end collision personal injury cases outside of medical malpractice — economic and non-economic damages are fully recoverable.
