Leaving an Accident Scene Before Police Arrive

Attorney Answer

It turns on whether anyone was hurt. In a damage-only crash, leaving your car and your information is a large part of what the law asks for — but the duty is defined by the statute, not by whether police have shown up. If anyone was injured, leaving before you have done everything the statute requires is what California's hit-and-run law punishes, and "I left my information" is not a complete defense.

California splits the duty into two statutes. Vehicle Code § 20002(a) covers a collision that results only in damage to property, including another vehicle: the driver must immediately stop at the nearest location that will not impede traffic, and then meet the identification duties the section goes on to impose — giving your name and address and vehicle information to the other driver or owner, or, if nobody is there to receive it, leaving that information in writing and notifying police (§ 20002(a)(1)-(2)). That written note is required by the statute, so leaving one is never the thing that gets you in trouble.

Vehicle Code § 20001(a) covers a collision that results in injury to another person or in a death. It requires the driver to immediately stop the vehicle at the scene, and it carries far heavier consequences: under subdivision (b), up to a year in county jail, a fine of $1,000 to $10,000, or both, and where the crash caused death or permanent, serious injury, two to four years in state prison or 90 days to a year in county jail.

Notice what neither statute says. Neither one makes the arrival of a police officer the moment the duty ends. Leaving on foot is not itself the offense; failing to complete what the statute requires is. And in an injury crash, whether the duties were satisfied is a judgment made later, by a prosecutor and possibly a jury, on facts including how badly someone was hurt and what you knew when you walked away. Injuries that seem minor at the scene do not always stay minor.

What you can do

1. If there is any chance a person was hurt, do not leave. Call 911, say someone may be injured, and stay.

2. Give the other driver or owner your name, address and vehicle information. If nobody is there to receive it, leave that information in writing where it will be found and notify police — that writing is required by Vehicle Code § 20002 and is the correct step.

3. Preserve what already exists: photos you already took, the other driver's information, dashcam footage, and any messages. Do not write out or post your own narrative of how the crash happened, and do not discuss it with anyone but a lawyer.

4. If police contact you, or the other side's insurer does, talk to a local criminal-defense attorney first. You can identify yourself; giving an account of the crash is a different thing, and it is the step where people hurt themselves.

5. 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. The duties in Vehicle Code §§ 20001 and 20002 are immediate — they run from the collision itself, not from any later date. Separately, a civil claim arising from the same crash runs under Code Civ. Proc. § 335.1 for injuries and Code Civ. Proc. § 338(c)(1) for vehicle damage. Criminal charging deadlines are a different question again, and which period applies depends on the facts of the crash. Have a local attorney review the dates on your specific facts.
