Always call 911 in case of emergencies like car accidents. Ask to get medical attention, and the 911 dispatcher will also contact a law enforcement officer to reach the scene. If anyone is injured on the scene or the damages exceed $1000, then it is mandatory to report the accident.
While you are waiting for them to arrive, try to collect information from responsible parties, witnesses, and passersby if you are physically able. Taking videos and photos of the damage will also help your claim. After the ambulance and police reach the scene, the reports will serve as valid evidence in your claim. Remember that the clock to file the claim starts ticking from the minute the accident occurred, and you got injured. In California, you only have two years from the accident date to file your claim, with certain exceptions. If you are filing a case against a government agency, the time is even more limited. You must contact us as soon as you have received medical care.
