What is required by the department for someone to maintain a valid driver's license?

Maintaining a valid driver's license requires compliance with court restrictions. When a driver has encountered legal issues that lead to restrictions or requirements imposed by a court—such as attendance at traffic school, limitations on driving times, or requirements for sobriety—meeting these conditions is essential for keeping their driving privileges intact. Failure to adhere to these restrictions can result in license suspension or revocation, highlighting the importance of compliance for lawfully maintaining a valid license.

The other options, while they may seem relevant in certain contexts, do not generally apply universally as requirements for maintaining a driver's license. Regular attendance at driving school, proof of residency, or passing a vision test are not standard continuous requirements for all drivers. Instead, they may apply under specific circumstances, such as for obtaining a new license or during the initial licensing process, rather than as ongoing obligations.
