Final answer:
You are required to inform the DMV within 30 days of changing your address to update your driver's license and voter registration, if applicable.
Step-by-step explanation:
When you move, especially when changing your address, you are required to inform the Department of Motor Vehicles (DMV) within 30 days of your new residency. This notification is particularly important for updating your driver's license information and ensuring that your voter registration is current, which may be tied to your DMV record, depending on your state, as is the case in California. Failure to update your address with the DMV can lead to complications such as not receiving renewal notices and may have legal implications.
