Proving a Rear-End Claim More Than a Year Later

Attorney Answer

Four things have to be proved, and the calendar is the urgent one. You have to show that the other driver fell short of ordinary care, that this caused the collision, that the collision caused your harm, and what that harm actually is. Because the crash was more than a year ago, have a lawyer check your deadline before you do anything else.

The standard of care comes from Cal. Veh. Code § 21703: "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." Cal. Civ. Code § 1714(a) turns that into liability: "Everyone is responsible, not only for the result of his or her willful acts, but also for an injury occasioned to another by his or her want of ordinary care or skill in the management of his or her property or person, except so far as the latter has, willfully or by want of ordinary care, brought the injury upon himself or herself."

Being rear-ended is a strong starting point, not an automatic win. A driver who runs into the car ahead has to explain it, and the usual explanations are that the car in front stopped suddenly for no apparent reason, that a third vehicle pushed the following car forward in a chain collision, or that a lane change put the front car where it was. Expect one of those.

Your own conduct, if any of it is in question, reduces the claim rather than destroying it. California is a pure comparative fault state, and the California Supreme Court reaffirmed and applied that system in Daly v. General Motors Corp., 20 Cal. 3d 725 (1978): a plaintiff who bears part of the blame has the recovery cut by that share rather than taken away.

What you can be paid is measured by Cal. Civ. Code § 3333: "For the breach of an obligation not arising from contract, the measure of damages, except where otherwise expressly provided by this Code, is the amount which will compensate for all the detriment proximately caused thereby, whether it could have been anticipated or not." In practice the medical records, the bills, the wage loss and the repair or value of the car do the proving. A claim with a long gap in treatment is harder to prove than the same claim with continuous records, and that is where a year-old case is usually won or lost.

What you can do

1. Ask a local personal injury attorney to review your deadline this week. Bringing a case in court is not something to work out from a general page, and the period is short enough that it drives everything else.

2. Collect the traffic collision report, photographs of both vehicles, and the names and contact details of any witnesses.

3. Collect your complete medical records and bills from the crash forward, including anything you paid yourself, and a record of the work you missed.

4. Ask any health plan that paid for your treatment whether it claims reimbursement out of a recovery, and get the answer in writing. That affects what reaches you, not whether you have a claim.

5. Preserve anything still in your control: the vehicle if it is unrepaired, photographs, and messages with the other driver or their insurer.

6. Do not sign a release, and do not accept a payment described as final, until a lawyer has read it.

7. Most lawyers offer a brief initial call at no cost, and a few minutes on your specific facts is worth more than any general guidance, including this page.

⏱ Time limits apply. A claim for injury to a person runs under Cal. Code Civ. Proc. § 335.1, which allows two years, and a claim for damage to the vehicle under Cal. Code Civ. Proc. § 338(c)(1), which allows three. Because your crash was more than a year ago, the shorter of those is close enough that only a lawyer looking at your actual dates can tell you where you stand. This page cannot calculate that date for you, and a missed one generally ends the claim.
