Which of the following statements about driving laws is true?

The statement that drivers are mandated to have their photos taken during the application process is accurate because the California DMV requires a photo to be taken as part of applying for a driver's license. This photo is crucial for identification purposes and is included on the driver's license. It helps prevent identity theft and ensures that the driver's identity can be confirmed when necessary.

The other options do not reflect the current regulations in California. For example, not all drivers undergo a background check, as the focus is primarily on the written and driving tests to assess the applicant's ability to operate a vehicle safely. Additionally, there are certain restrictions and requirements imposed on residents when applying for a driver's license, such as proof of residency and identity. Lastly, having a violation of traffic laws does not automatically block a license application; rather, specific serious offenses may affect eligibility but are evaluated on a case-by-case basis.
