Fault and Next Steps After Backing Out of a Space

Attorney Answer

A driver backing out of a space carries most of the fault in most of these collisions — but "most" is not "all," and California divides fault between drivers instead of handing the whole of it to one.

The root 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. A driver reversing into a lane of travel is moving into space they cannot fully see, which is why insurers usually start with the backing driver. But that is a starting point, not a verdict. The other driver's own conduct — speed in a lot, attention, whether they were driving the wrong way down an aisle — is weighed too.

That matters because of how California splits the result. In Daly v. General Motors Corp. the California Supreme Court reaffirmed and applied this state's pure comparative system, under which an injured person's recovery is reduced in proportion to their own lack of reasonable care rather than eliminated. Read from your side, a share of fault on the other driver reduces what you end up paying. It is a reason not to concede the whole of it before anyone has looked at the evidence.

Two further questions bear on this: the specific rule for backing a vehicle, and how the Vehicle Code's rules of the road apply inside a private lot. Those are questions for a local attorney rather than assumptions to build on.

On duties at the scene, Cal. Veh. Code § 20002(a) requires a driver 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; Cal. Veh. Code § 20001(a) applies the stopping duty where someone was injured. If you stopped and exchanged information, that part is behind you.

What the other driver can recover is measured by Cal. Civ. Code § 3333: the amount that will compensate for all the detriment proximately caused, whether or not it could have been anticipated. For a damaged car that generally means repair cost or value, plus losses like being without the vehicle. Your liability insurer ordinarily handles that claim and its defense under your policy. Cal. Veh. Code § 16000(a) also requires an accident report to go to the Department of Motor Vehicles after certain crashes, so ask the DMV or a local attorney whether it applies.

What you can do

1. Report the collision to your own insurer promptly — most policies require prompt notice, and late notice is a problem that costs nothing to avoid.

2. Preserve what already exists rather than writing something new: photographs of both vehicles and where they came to rest, the information you exchanged, and any messages since.

3. Ask the parking lot's business, in writing and today, to preserve any camera footage of the aisle. Lot video is usually overwritten within days.

4. Give your insurer the names and contact details of anyone who saw it, including passengers.

5. If anyone reports an injury, or the police contact you, speak with a local attorney before giving any statement.

6. Ask a local attorney whether the other driver's own conduct puts part of the fault on that side.

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 an injury claim on the two years in Cal. Code Civ. Proc. § 335.1 — the shorter of the two, and the one that catches people out when a claim arrives long after the repair is done. When each period started depends on your facts, so have a local attorney check the dates.
