Final answer:
You are required to file a Report Traffic Accident Occurring in California (SR 1) with DMV when you are involved in a collision that results in injury or death. This does not apply to situations like failing a smog test or changing your insurance company.
Step-by-step explanation:
You must notify law enforcement and file a Report Traffic Accident Occurring in California (SR 1) with DMV when you are involved in a collision and there is an injury. This is a legal obligation for drivers in the state of California when they've been involved in an accident that results in injury or death.
In contrast to being involved in a collision, failing a smog test or changing your insurance company does not require a Report Traffic Accident form to be filed with the DMV. However, other procedures may apply, like vehicle reinspection after a failed smog test, or updating your insurance details with the DMV upon changing providers.
