What must a foreign driver's license holder do after 30 days to operate a vehicle in Guam?

To operate a vehicle in Guam, a foreign driver who has been in the territory for more than 30 days must apply for a Guam driver's license. This process is necessary to ensure that all drivers meet local safety and legal requirements, which may differ from those in their home countries. Additionally, taking a written exam may be required to confirm knowledge of Guam's specific traffic laws and regulations, which helps to promote safe driving practices within the community.

By requiring foreign drivers to transition to a local driver's license, Guam aims to maintain a standard that ensures all drivers on the road have a proper understanding of the traffic rules, contributing to overall road safety. This is particularly important in tourist areas where a variety of road users may have different levels of familiarity with local driving conditions.
