California Vehicle Code Section 21703 prohibits following too closely and creates a presumption that the rear driver is at fault in a rear-end collision. This presumption shifts the burden to the defendant to show an emergency or sudden stop by the lead driver. Most rear-end collisions in California result in clear liability against the following driver.
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.
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.
"The driver of a motor vehicle shall not follow another vehicle more closely than is reasonable and prudent, having due regard for the speed of such vehicle and the traffic upon, and the condition of, the roadway."
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.
California rear-end collision 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).
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.
In California, Vehicle Code Section 21703 creates a presumption of fault against the rear driver for following too closely. This presumption is rebuttable — the rear driver can show the lead driver made a sudden, unexpected stop or that some other emergency caused the collision. However, in a typical rear-end accident, the following driver bears clear liability.
Rear-end collision damages in California include: all medical expenses (emergency care, physical therapy, chiropractic care, MRI and imaging, future treatment); lost wages during recovery; lost earning capacity if the injury is permanent; property damage to your vehicle; and non-economic damages including pain and suffering, emotional distress, and loss of enjoyment of life. California does not cap these damages.
Two years from the date of the accident under California Code of Civil Procedure Section 335.1. For claims against government entities (e.g., a city vehicle rear-ended you), the Government Claims Act requires a written administrative claim within six months under Government Code Section 945.4. Missing either deadline permanently bars the claim.
Call 911 and stay at the scene. Accept emergency medical evaluation even if you feel uninjured — whiplash and soft-tissue injuries often manifest hours or days later. Photograph both vehicles, the scene, skid marks, and any visible injuries. Collect the other driver's insurance information and any witness contact information. Do not give a recorded statement to the other driver's insurance company without legal advice.
Yes. California's pure comparative fault system from Li v. Yellow Cab Co. (1975) allows recovery regardless of your fault percentage. If you contributed to the accident — for example, by stopping suddenly without warning — your damages are reduced proportionally but not eliminated. A rear-end victim found 20% at fault recovers 80% of total damages.
California Vehicle Code Section 21703 prohibits driving a motor vehicle so closely behind another vehicle that the driver cannot stop safely. When a rear-end collision occurs, courts apply a rebuttable presumption that the following driver violated Section 21703. To overcome this presumption, the following driver must prove a sudden stop, equipment failure in the lead vehicle, or similar emergency — not simply that the lead driver braked quickly.
