Final answer:
The displayed license or registration must be the original or a duplicate issued by the department, with an updated photo reflecting the holder's current appearance. For updates, such as changes in address, the DMV requires legible information that matches their records. Commercial drivers must maintain a California resident address on their license.
Step-by-step explanation:
The registration or license on display as part of the California Department of Motor Vehicles (DMV) requirements must either be the original or a duplicate issued by the department. It is mandatory to have a current photo (2" by 2") taken within the previous two years of the individual whose name appears on the certificate. This is to ensure that the identification presented reflects the current appearance of the holder.
Updating your information with the DMV is essential. If there is a change in the information initially provided to the DMV, such as an address, it is important to make the update. However, if you're a commercial license holder, maintaining a California residence address is crucial. Failure to do so could result in a downgrade of the driver license to a non-commercial status, impacting your legal ability to operate commercial vehicles.
