Can an Indian Drive in Guam? — IDP Recommended + the Side Switch to the Right

Guam is a US territory in the western Pacific, and that status answers most of what an Indian visitor needs to know about driving here — the rules, the signs and the side of the road all follow the American pattern.

The verdict for Indian licence holders

You can drive in Guam on your Indian licence for a short visit, and an International Driving Permit is recommended to carry with it. As US territory the rules mirror the mainland, where a foreign licence with an IDP is the standard combination tourists use. Arrange the IDP in India before you fly, since you can’t get one locally, and keep it with your Indian licence and passport. Check exactly what you need on the Driving Permit Checker.

You switch to the right — but the signs are in English

India drives on the left; Guam drives on the right, US-style. The reversal is your main adjustment, and the first day is when the old reflex bites hardest — at junctions, pulling out of a car park, and at the four-way stops that are common across American road networks. The compensation is that everything else is familiar from films and travel: signage and markings follow US conventions and are in English, so you won’t be deciphering the road, just relearning your side of it. Take the first hour somewhere quiet.

What the data does and doesn’t tell us

Honestly, Guam-specific posted speed limits and a confirmed drink-drive figure aren’t well documented in our sources, so I won’t invent numbers. What’s reliable: US-territory rules apply, signage is in English, the emergency number is 112, and the capital is Hagåtña. As a rule of thumb, US drink-drive enforcement is strict, so treat alcohol as off-limits before driving and follow the posted mph signs. For the broader picture see our Guam driving guide.
