US Drivers in the Dominican Republic 2026: Bring the IDP

You can drive in the Dominican Republic with your US license, but pack an International Driving Permit with it. The only official rule written down for visitors comes from Global Affairs Canada: a foreign licence is good for up to 30 days, and an IDP must be carried alongside it. Traffic keeps to the right, as at home. The alcohol limit is 0.05%, lower than the 0.08 you know. The bigger adjustment is the road itself: the U.S. State Department says the country has the highest road crash death rate in the world and suggests visitors consider hiring a professional driver instead.

The permit question, answered

The State Department’s Dominican Republic page talks at length about road dangers but does not spell out how long an American license is valid. Ottawa’s advice fills the gap with the 30-day window and the IDP requirement, and the UK government’s permit table lists the 1949 IDP for the country. That is exactly the permit AAA sells in the US, and both the Dominican Republic and the United States are parties to the 1949 Geneva Convention. Buy it before you fly; it cannot be issued once you land. For a stay past 30 days, ask the rental company and the Dominican authorities what applies. For a Caribbean trip with more than one island, check each stop in the driving permit checker.

Keep your passport out of the rental contract

This is a Dominican-specific warning from the State Department. Car rental companies sometimes hold on to a renter’s passport if the bill is unpaid or the car comes back damaged. The department recommends not leaving your passport with the agency at all. If it is retained anyway, call the U.S. Embassy. Show the passport at the counter, then put it back in your bag.

What you will meet on the road

The State Department’s list of common hazards reads like a description of a normal day in Santo Domingo traffic:

• cars with no headlights or taillights at night
• animals on the road
• missing manhole covers and large potholes
• scooters and motorcycles weaving through lanes
• vehicles on sidewalks or driving against traffic
• junctions with no stop signs, and drivers running stop lights

Global Affairs Canada adds that the main highways between cities and tourist areas are generally in good condition, but rural roads are poorly maintained, with unmarked speed bumps and poor lighting. Ottawa also advises against using or renting the motorcycle taxis known as motoconchos. Drive long legs in daylight and watch for limit changes between town and open road.

Rules that work differently from the US

Traffic laws are inconsistently enforced, the State Department says, but some are applied hard:

• Seat belts are required for car passengers, and helmets for motorcyclists. Violators can be fined.
• No child car seat law exists. If you are travelling with children, bring or reserve seats yourself.
• Police can stop you for using a phone without a hands-free device.
• In a collision between a car and a motorcycle, the car’s driver is usually found at fault, whatever happened. Given how many scooters there are, that changes how much space you should give them.

After a crash

In serious accidents drivers are often detained, even when not at fault, until a court ruling or a signed waiver. Typically only the driver is taken into custody, not the passengers. Dial 911, stay at the scene and contact the U.S. Embassy. On the toll highways, free 24-hour road assistance is on 1 829 688 1000.

Bribes and tickets

Americans have reported traffic police asking for money instead of writing a ticket. The State Department’s advice is to refuse politely and ask for an official ticket. Keep your documents together so the stop stays about paperwork.

Drinking and driving

Can you drink and drive in the Dominican Republic? Legally, up to 0.05% according to the WHO profile, which is less than many Americans would reach before feeling any effect at home. Add unlit roads and unpredictable traffic after dark, and the only sensible amount is none. The full rules are in the Dominican Republic driving guide, and the speed limit map helps before a longer drive.
