Eligibility, Required Documents, and Types of Guam Licenses

Eligibility, Documents, and Guam's License Classes

Quick Answer: You may begin the process at 15 and a half. If you are under 18, a parent or legal guardian must be physically present to sign before you take the written test. Visitors holding a valid U.S. mainland license may drive for 30 days after arrival; foreign license holders from recognized jurisdictions also get 30 days, then must pass Guam's written and road tests.

Driving is a privilege

Guam law treats driving as a privilege extended by the government, not a right you hold independently. This is not a philosophical footnote — it is the legal foundation that lets the Department of Revenue and Taxation suspend or revoke a license administratively, and it is why implied-consent rules (Chapter 7) can penalize you for refusing a chemical test even before any conviction.

Expect at least one question that tests whether you understand this framing.

Minimum age

The minimum age to begin is 15 and a half. That is the entry point to Stage 1 of the graduated system covered in the next section, not the age at which you receive a full license.

The under-18 rule that stops applications at the counter

If you are under 18, a parent or legal guardian must be physically present to sign the application before you take the written test. A signed note, a phone call, or an accompanying older sibling does not satisfy this. Minors regularly lose a scheduled test slot because the adult who came along was not the parent or legal guardian.

The application itself

The Guam application is a sworn document containing roughly a dozen declarations covering your identity, residency, physical and mental condition, any license previously held in another jurisdiction, and any suspension or revocation history. Because it is sworn, a false statement is not merely an administrative problem — it is a legal one, and it is grounds to deny or cancel the license.

Acceptable identification

Guam accepts a range of identity documents, including:

• U.S. or foreign passport
• Military identification
• Guam identification card
• Certificate of naturalization
• Alien registration card
• U.S. mainland photo identification
• Firearms identification card

One rule causes more rejections than any other: the name must match exactly across your documents. A married name on one document and a maiden name on another, or a middle initial that appears on one and not the other, will stop the application. If your documents disagree, resolve that before your appointment — bring the marriage certificate or court order that bridges the two names.

Guam offers the option of a REAL ID compliant license or identification card, and has done since 25 June 2018 — it is a choice, not the only product. A non-REAL-ID Guam license is still available. If you want the REAL ID version you must supply the fuller federal identity documentation, which is why applicants report a stricter document check than they remember from years past.

Visitors and new arrivals: the 30-day rule

This is one of the most practically useful facts in the guide.

Recognized foreign jurisdictions include Palau, the Federated States of Micronesia, the Republic of the Marshall Islands, Japan, Taiwan, the European Union, Canada, New Zealand, Korea, the Philippines, and Australia. The regional Pacific entries matter enormously on Guam, where movement between the island and the Freely Associated States is routine.

Note the asymmetry: a mainland U.S. license converts administratively, while a foreign license generally requires you to pass both the written and the road test. There is also a federal-employee exception for certain personnel operating under federal authority.

Guam's license classes

The two ages worth memorizing are Chauffeur at 18 and Taxi at 21. Candidates routinely confuse them, and the distinction is a natural test question because both are commercial-purpose licenses with different thresholds.

Common traps in this section

• Assuming the 30-day visitor allowance is 90 days, as it is in some states — on Guam it is 30.
• Assuming a foreign license converts on paper — for most jurisdictions it does not; you test again.
• Assuming any adult can sign for a minor — it must be the parent or legal guardian.
