California uses the fault system for resolving car accident cases, meaning the driver at fault for a crash assumes liability for all the resulting damages. All drivers are required by state law to have auto insurance that provides bodily injury liability coverage and property damage liability coverage. Therefore, if another driver hits you, you can file a claim against their auto insurance policy to seek compensation for the losses they inflicted. However, if this is not enough to fully repay your damages, you would need to file a personal injury claim against the at-fault driver.
