Guam Driving Advice and Car Hire Info

Driving In Guam

Guam drives on the right and you can use the photo licence of any country to drive here for up to 30 days, providing it’s written in Roman alphabet. Drivers from other countries need their own licence plus an international driving permit. After 30 days you need to apply for a local licence. As a US territory, most of the road rules are the same in Guam as in USA. Speed limits, however, are lower at 35 MPH on main roads  25mph in towns and 15 mph near schools.

The United States Military began to develop and construct roads on the island in 1941 and that has resulted in a well maintained and efficent system of over thirty state highways numbers GH1 -GH34. Main routes on the island include-

GH1 or Marine Corps Highway, which runs in a southwest-to-northeast direction, from the Naval Base in Santa Rita past the town if Piti and the island’s capital, Hagåtña to the International airport and Anderson airforce base.

GH-4 is the major route around the southern half of the island .The highway begins at the south end of GH-2 in Umatac heading south to Merizo and then following the coast to Inarajan and then north to Talofofo and Yona, where it meets the GH-17 Cross Island Road. It then turns northwest and passes through Chalan Pago-Ordot and Sinajana before finally reaching Hagåtña, at the  GH-1 junction.

For anyone familiar with driving in the USA ,Guam won’t pose any driving problems though the local driving style will probably seem quicker and more aggressive than the USA. The island is small so there are no great distances to travel anywhere and roads are well signposted so it’s difficult to get lost.

Although I try and keep the information in the site updated as much as possible, in a rapidly moving world, situations can change daily. Therefore please use the site as an approximate guide, and in conjunction with other resources in order to form your view on driving conditions, roads, safety etc.
