Rear-Ended by an Uninsured Driver in California — Legal Information | Got Reared Law

Rear-Ended by an Uninsured Driver: Overview Under California Law

Approximately 16-17% of California drivers carry no insurance. When an uninsured driver rear-ends you, the primary recovery mechanism is your own uninsured motorist (UM) coverage under California Insurance Code Section 11580.2. California requires UM/UIM coverage to be offered with every auto policy. UM coverage pays for your medical expenses, lost wages, and pain and suffering — up to your UM policy limits.

California rear-end collision law is governed primarily by Vehicle Code Section 21703 (following too closely), the rebuttable presumption of fault against the rear driver, and California's pure comparative fault system from Li v. Yellow Cab Co. (1975). The victim's recovery encompasses all economic damages (medical expenses, lost wages, property damage) and non-economic damages (pain and suffering, emotional distress) without any cap under California personal injury law.

CVC 21703 and the Presumption of Fault

California Vehicle Code Section 21703 prohibits following another vehicle more closely than is reasonable and prudent. In a rear-end collision, a rebuttable presumption arises that the following driver violated this statute. The following driver must produce evidence to rebut the presumption — typically a sudden, unexpected stop by the lead driver or an emergency — failing which the presumption stands and establishes the following driver's negligence.

Comparative Fault in Rear-Ended by an Uninsured Driver Cases

California's pure comparative fault system allows recovery even if the rear-end victim was partly at fault — for example, by stopping abruptly or driving with non-functional brake lights. The victim's recovery is reduced proportionally by their fault percentage but is not eliminated. In multi-vehicle rear-end cases, Proposition 51 (Civil Code Section 1431.2) allocates non-economic damages among defendants proportionally while maintaining joint and several liability for economic damages.

Damages Available After a Rear-Ended by an Uninsured Driver

California rear-ended by an uninsured driver victims can recover: all past and future medical expenses; lost wages and earning capacity; vehicle property damage including diminished value; non-economic damages (pain, suffering, emotional distress, loss of enjoyment of life) — uncapped in California; and punitive damages under Civil Code Section 3294 when the rear driver's conduct constitutes malice (DUI, intentional brake-check, reckless speed).

Statute of Limitations

Two years from the date of the accident under CCP Section 335.1. Government entity claims: six months under Government Code Section 945.4. Minor victims: tolled until age 18 under CCP Section 352. Missing these deadlines permanently bars the claim.
