Joint Region Marianas - Naval Base Guam

The mission of Naval Base Guam is:

• To support the forces of the US Pacific Fleet
• The warfighters based on Naval Base Guam
• The warfighters serviced and supplied by Naval Base Guam
• The commands which provide support to the warfighters
• The families of those stationed at Naval Base Guam

Guam is situated in a prime tropical cyclone formation area of the western Pacific and cyclones can and do occur. Typhoons can occur throughout the year but are more likely during June through December. Homes are built to be typhoon resistant and can handle the weather. Although recovery is sometimes long and difficult, Guam and its people are practiced in storm recovery and deal well with the situation. In order to increase your comfort during recovery it is recommended that you bring a generator as generators on the island are costly and hard to find when needed.

Guam law requires all civilian employees and military dependents to obtain a Guam driver's license within 30 days of arriving on Guam. If they have a current U.S. state or territory driver's license they are exempt from taking either a written examination or demonstration test but must surrender their current driver's license to obtain a Guam license. Active duty military members with a valid U.S. driver's license are not required to obtain a Guam license.

If their stay is less than 30 days they are not required to obtain a Guam driver's license. If their stay is more than 30 days, but less than 1 year, they can extend their current stateside license but must register their license with Department of Revenue and Taxation. Upon approval by Department of Revenue and Taxation, a registration fee is assessed and a Certificate of Registration is issued with the licensee's name, age and the expiration date of the certificate and the current driver's license number.

For motorcycle licenses if the current stateside license has a motorcycle endorsement your Guam license will be endorsed by Department of Revenue and Taxation without the required written and road tests. Joint Region Marianas policy states that all Naval personnel operating a motorcycle must attend a Motorcycle Safety Course. Service members who have passed the course at other installations are still required to take the course here. Guam does not have a helmet law but Joint Region Marianas policy states that all military personnel stationed on Guam will wear a helmet when operating or riding a motorcycle on or off base. For more information on Installation Safety, please contact (671) 339 - SAFE (7233). 

Guam's roads are not well lit or marked and roads tend to become very slippery when it rains. Drive with caution.
