Common questions
Where does this data come from?
These figures aggregate public California crash data (CCRS / CHP, data.ca.gov). They are educational summaries and may differ from other official tallies.
What is the statute of limitations for a car accident in California?
The general deadline to file a personal injury lawsuit after a car accident in California is two years from the date of the crash. Claims against a government entity have a much shorter notice deadline (often six months). Confirm your specific deadline promptly.
Do these statistics predict where a crash will happen?
No. They describe historically reported crashes and are not a prediction of future events or a measure of fault in any specific incident.
