How often must driver's licenses be renewed in Guam?

Driver's licenses in Guam must be renewed every eight years. This is in line with many jurisdictions that establish renewal periods to ensure that the information on the license remains current and that drivers maintain their road safety knowledge. Renewing a license at this interval allows the local authorities to update the information on the license, such as changes in address or personal details, and to verify that a driver has not developed any impairments that would affect their ability to operate a vehicle safely. The eight-year renewal period also helps to manage administrative resources effectively while ensuring that drivers are regularly reminded of their driving privileges.
