My question involves an injury that occurred in the state of: California

My car was hit when it was parked on a street. Another car, next to it was hit too. I ordered police report and discovered that the driver who hit those cars had a DUI and he tried to escape (hit and run), but was unable to do it due to the damage to his car. The driver is 18 years old. His insurance has only minimum coverage of $5000. Police report says in two witness statements that he first hit one car, and was entangled in it. He tried to free his car, succeeded, but after he freed his car he hit another car. The question is it considered to be one accident, or two separate accidents? If it's two accidents, than the insurance can cover both damaged cars up to $5000 each, while $5000 for both cars is not enough.
His insurance says that it's one accident.
