Final answer:
A Report of Traffic Accident Occurring in California (SR 1) must be filed with DMV when involved in a collision resulting in injury, not for smog failures or insurance changes. Voter registration can be updated through the DMV if moving within the same county or by using their resources for new registrations.
Step-by-step explanation:
You must file a Report of Traffic Accident Occurring in California (SR 1) with DMV when you are involved in a collision and there is an injury. This form is crucial for legal and insurance purposes, documenting the event for the California Department of Motor Vehicles. When your vehicle fails a smog test or you change your insurance, filing an SR 1 form isn't required. However, it's essential to note that the DMV also handles voter registration updates. If you have moved within your county, the DMV will update your voting address. Should you move to a new county or need to re-register, you can obtain the voter registration form from the DMV, call 1-800-345-VOTE, or visit the Secretary of State's website.
