Who has the authority to revoke a driver's license?

The authority to revoke a driver's license lies with government or state authorities. This typically includes agencies such as the Department of Motor Vehicles (DMV) or similar entities responsible for overseeing driving regulations. These authorities have the power to suspend or revoke licenses based on various factors, such as traffic violations, unsafe driving records, or failure to comply with legal requirements, such as insurance mandates.

In contrast, the courts can have a role in license revocation as part of a legal judgment but do not operate independently to revoke a license without the influence of the state's driving regulations. An individual cannot unilaterally decide to revoke their own license; that would be counterintuitive as a license is a privilege granted by the state. Friends and family do not have any formal authority over a driver's license and cannot revoke it. Hence, the ability to revoke a driver's license is exclusively in the hands of designated state authorities, which is why they are recognized as the correct answer.
