Driving in Dominica: 25 Tips for Americans

💡Quick Answer

Driving Dominica is exhilarating but very different from home. You drive on the LEFT, the roads are steep, narrow and winding, and you must buy a local visitor's permit (about US$12 / EC$30) with an IDP recommended alongside it. And to be clear: this is Dominica the Nature Island (dom-in-EE-ka) — the small, English-speaking island — not the Dominican Republic of Punta Cana and Santo Domingo. These 25 tips will save you fines and surprises.

Before You Go (Tips 1–5)

The most important preparation happens before you ever land at Douglas–Charles Airport (DOM). Get these five things sorted at home and the rest of your trip gets far easier.

  1. Get an IDP before you leave the US. Apply through AAA or AATA — these are the only two US-authorized issuers. An IDP cannot be issued on-island, so you must carry it out with you. It translates your US license and is recommended alongside the required local permit.
  2. Plan to buy the local visitor's permit. Every visitor must buy a temporary visitor's driving permit for about US$12 / EC$30. You can pick it up at the rental agency, at Police Headquarters in Roseau, or at the airport. Budget for it and factor a few minutes into your pickup.
  3. Reserve a 4x4 or SUV — and an automatic if you need one. Dominica's mountain roads reward higher clearance and grip. Manual transmission is common here, so if you cannot drive a stick, reserve an automatic well ahead of time or you may not find one on arrival.
  4. Download offline maps. Use Google Maps offline areas or maps.me before you go. Once you head inland through the rainforest, mobile signal is patchy and you do not want to lose navigation on an unmarked mountain road.
  5. Confirm it is Dominica, the Nature Island — not the Dominican Republic. They are entirely different countries with different airports, currencies and driving rules. Double-check your flights land at DOM (Douglas–Charles) in the Commonwealth of Dominica, not in the Dominican Republic.

At the Rental Counter (Tips 6–10)

A few minutes of care at pickup prevents most of the disputes and charges travelers run into later. Handle these five before you drive off the lot.

  1. Buy or collect your visitor's permit here. Most rental agencies can issue the temporary permit on the spot. Keep it clipped together with your US license so you can produce both at any checkpoint.
  2. Present your IDP unprompted. Hand over your IDP with your US license even if the clerk does not ask. It reassures the agency that your license is valid and keeps your paperwork consistent for any later police stop.
  3. Inspect and photograph the car for existing damage. Walk the whole vehicle and photograph every scrape, dent and wheel before you leave. On these narrow roads, dings are common, and you want proof of what was already there.
  4. Take the super-CDW or excess waiver. Narrow, walled and rocky roads mean brushes and scratches happen. Paying a little extra for a zero-excess or super collision waiver is well worth it here.
  5. Ask about fuel, the spare and the emergency number. Confirm whether the car takes petrol or diesel, check the spare tire and jack are present and usable, and save the agency's emergency contact in your phone before you drive away.

On the Road: Defensive Habits (Tips 11–15)

Dominica's roads demand active, defensive driving every minute. These five habits are the difference between a relaxed drive and a white-knuckle one.

  1. Keep LEFT — talk yourself through it. This is the number one adjustment for Americans. Say "keep left" out loud at every junction, and re-check your position after every stop, gas fill-up or scenic pull-over, when muscle memory tries to pull you right.
  2. HONK before blind corners. A short toot before a blind bend warns oncoming traffic you are there. Locals do it constantly — it is basic safety and courtesy on Dominica, not rudeness. Get in the habit early.
  3. On single-lane mountain stretches, the vehicle going UPHILL often has priority. Where the road narrows to one lane, the car climbing usually has right of way because reversing downhill is easier and safer. Be ready to back up to the nearest passing spot.
  4. Scan constantly for potholes, gravel and rainy-season slides. The road surface changes without warning — potholes, loose gravel, and in the June-to-November rainy season, landslides and rockfall. Keep your eyes on the surface ahead and your speed low enough to react.
  5. Expect livestock, dogs and pedestrians. Rural roads have no sidewalks, so goats, dogs and people (including at night) share the tarmac with you. Slow down through settlements and around bends where you cannot see far ahead.

Roseau & Town Driving (Tips 16–20)

The capital, Roseau, and towns like Portsmouth and Marigot are tight and busy. In town, slower and more patient always wins.

  1. Roseau streets are narrow, one-way and busy. The old capital was not built for modern traffic. Go slow, expect one-way systems, and seriously consider parking on the edge of town and walking in rather than threading the center.
  2. Do not block the road on blind bends or bus stops. If you stop to take a photo or drop someone off, never do it on a blind corner or where buses pull in. A stopped car on a narrow bend is a real hazard here.
  3. Slow to about 20 mph through villages. People, children and vendors are close to the road in every village you pass. Ease right off the accelerator — roughly 20 mph or less — whenever houses line the route.
  4. Watch for buses (shared vans) stopping suddenly. Dominica's shared minibuses stop wherever a passenger flags them or wants off, often with little warning. Leave extra following distance behind any bus.
  5. Fill up in Roseau or Portsmouth. Fuel stations are sparse outside the main towns and some close early or on Sundays. Top up whenever you are in Roseau or Portsmouth rather than assuming you will find a station out in the countryside.

Mountain & Rural Driving (Tips 21–25)

Dominica has no highways or motorways at all — every cross-island journey is a mountain road. Distances look short on the map but take far longer to drive. Plan for it.

  1. There are no motorways — every cross-island leg is a slow mountain road. A trip that looks like 20 miles can take 1.5 to 2.5 hours over the ridges. Do not judge travel time by distance; judge it by terrain and add a generous buffer.
  2. Use low gears on steep descents. Riding the brakes down long, steep grades overheats them. Shift into a low gear and let engine braking hold your speed, saving the brakes for when you actually need them.
  3. Avoid driving after dark. Rural roads are unlit, have no shoulders, and hide potholes, animals and pedestrians in the black. Where you can, finish your driving before nightfall and enjoy the evening off the road.
  4. After heavy rain, expect water across the road. Downpours can send water and debris over the tarmac and occasionally close roads entirely. Never try to cross fast-flowing water — turn around and find another route or wait it out.
  5. Keep the tank above half and carry water. With sparse fuel and long slow legs, keep at least half a tank, carry drinking water, and have a paper or offline backup of your route in case signal drops. A little self-sufficiency goes a long way inland.

What Americans Get Wrong

A handful of home habits simply do not transfer to a left-side, right-hand-drive island. These are the ones that trip visitors up most.

  • There is no turn-on-red rule to assume. Do not treat junctions the way you would at home — take each one on its own terms and give way as marked or as traffic dictates.
  • The horn is communication, not aggression. A toot means "I am here" on a blind corner, not "get out of my way." Use it freely and do not take offense when others do.
  • Roundabouts go CLOCKWISE. Because you drive on the left, traffic circles run clockwise and you give way to the RIGHT. Look right first, not left, as you approach.
  • Your controls are mirrored. In a right-hand-drive car the indicator and wiper stalks are usually swapped from your US car, so you may flick the wipers when you mean to signal at first. Expect it and adjust.
  • Pedestrians and vendors may be in the road. In towns, people walk and sell close to or in the roadway. Yield generously and never assume they will step aside for you.

At a Police Stop or Checkpoint

The Commonwealth of Dominica Police Force runs occasional checkpoints, and a stop is nothing to worry about if you stay calm and organized.

  • Be calm and polite — officers speak English, so there is no language barrier to navigate.
  • Have your US license, visitor's permit, IDP and rental papers ready to hand over together.
  • Occasional checkpoints are a normal part of driving here; treat them as routine.
  • If you are asked to pay anything on the spot, ask for an official receipt.
  • Do not argue at the roadside. If you disagree with something, stay courteous and follow up properly afterward.

If You Have an Accident

Even careful drivers can have a bump on roads this tight. Knowing the steps in advance keeps a small incident from becoming a big problem.

  • Stop immediately and check everyone for injuries before anything else.
  • Call the police on the emergency number 999 for anything beyond a light scratch.
  • Do not move seriously damaged vehicles until police attend, if they require it.
  • Photograph everything — both vehicles, the road, the position, and any damage.
  • Get the other driver's name, contact and vehicle details.
  • Call your rental agency's emergency line to report the incident.
  • Have your visitor's-permit and IDP paperwork ready — it will be asked for.

A Few Useful Local Phrases

Everyone on Dominica speaks English, so you never strictly need another language — but a little French Creole (Kwéyòl) is warmly received and a friendly greeting opens every interaction on-island.

  • Bonjou — good morning
  • Bonswè — good afternoon / evening
  • Mèsi — thank you
  • Souplé — please

A cheerful "good morning" in English works everywhere too — leading with a greeting is simply how things are done here.
