You are required to notify DMV by filing a Report of Traffic Accident Occuring in California (SR-1) form if:

  1. You change your insurance company.
  2. You were involved in a collision with an injury. ✓
  3. Your vehicle fails a smog test.

Answer: B. You were involved in a collision with an injury.

You must file the SR-1 form when you are involved in a collision in which someone was injured or killed.

Why this is the answer

The handbook says each driver must send DMV a Report of Traffic Accident Occurring in California when a collision causes more than $1,000 in property damage or when anyone is injured or killed, even if the injuries are minor. It also says you file whether or not you caused the collision, and even if it happened on private property. Because the injury collision is one of the listed triggers, the SR-1 requirement applies.

Why the other answers are wrong

Remember it

Think crash report, not paperwork changes: injury or major property damage is what triggers the SR-1.
