Who is allowed to get a copy of the crash report?
California limits crash reports to people with a proper interest. That includes drivers, injured people, passengers, vehicle or property owners, parents of injured minors, guardians, and their lawyers or insurance companies. You will usually need ID and the report number, date, and location. A lawyer can request it for you.
- The rule is in Vehicle Code §20012.

What is the timeline for a government claim in California?
For an injury, you generally have six months to file the claim. The agency then has 45 days to act, and silence counts as a denial. After a written denial you usually have six months to sue. If no proper written notice is sent, the lawsuit deadline is generally two years.
| Stage | Usual deadline | Law |
|---|---|---|
| 1. File the claim | Within 6 months of the injury | Gov. Code §911.2 |
| 2. Missed it? Ask to file late | Within a reasonable time, no later than 1 year | Gov. Code §911.4 |
| 3. Agency decides | 45 days; no answer counts as a denial | Gov. Code §912.4 |
| 4. File the lawsuit | 6 months after written denial notice; 2 years if no proper notice | Gov. Code §945.6 |
| 5. Late claim denied | Ask the court for relief within 6 months | Gov. Code §946.6 |
Exceptions can shorten or lengthen these dates. For the general two-year rule and other deadlines, read how long you have to file a personal injury claim in California.
