Disputed Backing Collision and Illegal Parking Claims

Attorney Answer

Who was moving is decided on evidence, not on who sounds more certain — and if you each turn out to carry part of the fault, California splits it rather than picking one of you to pay everything.

The rule is Cal. Civ. Code § 1714(a): everyone is responsible for an injury occasioned to another by want of ordinary care in the management of their property or person, except so far as the injured person has, by want of ordinary care, brought the injury upon themselves. Both halves of that sentence apply to both drivers. Neither your age nor his has any part in it.

What the second half means in practice comes from the courts. In Daly v. General Motors Corp. the California Supreme Court reaffirmed and applied California's pure comparative system, under which a person's recovery is reduced only to the extent their own lack of reasonable care contributed to the injury. So the argument is not really "who is at fault" — it is what proportion each of you carries, and the answer can be split any way the evidence supports.

On your parking question, California has its own parking statutes, and local ordinances often add their own rules about parking on a street. That is a question for a local attorney or the city's own code, and it should not be answered by guesswork.

But the more important point is the one underneath your question. Even if the other car was parked illegally, that generally does not decide who pays. Illegal parking is a fact that goes into the fault allocation under § 1714(a); it does not relieve a moving driver of the duty to use ordinary care, and it does not automatically make the parked car's owner responsible for the whole loss. It is a factor, not a trump card. The same is true of who was backing: it points strongly, but it is still one input.

The pre-existing damage on your bumper is where you can actually do something. Insurers and body shops routinely separate old damage from new by matching height, direction, paint transfer and the pattern of contact. Documentation of what your bumper looked like before the incident — earlier photographs, repair invoices, an inspection report, even dated pictures on your phone — is the difference between an argument and a record. Cal. Civ. Code § 3333 measures any damages as the amount that will compensate for all the detriment proximately caused by the collision, which by definition does not include damage that was already there.

One last thing on duties at the scene: Cal. Veh. Code § 20002(a) requires the driver of a vehicle involved in an accident resulting only in damage to property, including vehicles, to stop immediately at the nearest location that will not impede traffic and to identify themselves to the other owner.

What you can do

1. Gather any photograph, invoice or record that shows the condition of your bumper before this incident, and put it all in one file.

2. Photograph both vehicles now — the damage heights, the paint, the angles — and where each car was positioned relative to the curb.

3. Give your insurer the names and contact information of the people who were with you, and let them be interviewed as witnesses.

4. Report the incident to your insurer with the facts you observed, and let it handle the dispute rather than arguing it directly with the other driver.

5. Ask a local attorney, or check your city's own parking rules, about the distance question — and about whether it would change anything here.

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 damage to a vehicle runs on the three years given by Cal. Code Civ. Proc. § 338(c)(1), and any injury claim on the two years in Cal. Code Civ. Proc. § 335.1. When each period started depends on your facts, so have a local attorney check the dates rather than assuming a disputed claim goes away on its own.
