How to renew a vehicle inspection — how it works anywhere

Written from published rules on 4 September 2026. Not monitored for changes since. A starting point, not official advice — confirm anything that matters with Department of Revenue and Taxation (DRT) / Division of Motor Vehicles.

Renewing a vehicle inspection in Guam involves taking the vehicle to an authorized inspection station to verify that it meets safety and equipment standards. Upon passing, the station issues a certificate which must be presented when registering the vehicle with the Department of Revenue and Taxation.

Your timing

Most vehicle owners begin the process at least 30 days before their current registration expires. This ensures that any necessary repairs identified during the inspection can be completed before the registration deadline, as inspections and registration renewals are linked processes.

Start 30 days ahead
