The Collectivity of Saint Martin — commonly referred simply as Saint Martin — is an French overseas collectivity in the northeastern Caribbean. It occupies the northern part of the island of Saint Martin, while the southern part belongs to the Dutch constituent country of Sint Maarten. The collectivity was once part of Guadeloupe until 2007, when it became a separate overseas entity of France. The territory is a popular tourist destination, known for its white-sand beaches and turquoise waters, low green hills and tropical vegetation, coral reefs, marine wildlife and a warm tropical climate year-round, an with economy that is reliant on tourism, trade, hospitality, construction, yachting and marine services.
The capital of the collectivity is Marigot. Located on the western coast, the town serves as the administrative and commercial centre of the territory, and as a hub for markets, cafés and ferry connections. Marigot reflects the island’s blend of French and Caribbean characteristics, with notable features like colonial-style buildings, colourful streets, traditional open-air markets, marina areas with yachts and waterfront restaurants, and Fort Louis — a historic fort overlooking the bay.
Hurricanes are the most significant threat, especially from June to November. Other hazards include coastal flooding, earthquakes, landslides and droughts.
As a French overseas collectivity, Saint Martin follow French traffic laws, where standard tickets usually offer a discounted rate if paid within 15 days, and would increase the penalty amount if not paid within 45 days. Common driving and traffic offences include the following:
Other offences that tourists normally get in trouble for are:
The official language of Saint Martin is French, but English is also spoken.
Vehicles drive on the right side of the road. The minimum legal driving age is 18, while the age to rent a car is 21. Rental companies would require drivers to have held a valid licence for at least 1 – 2 years in order to rent, and would apply a daily young driver surcharge to, and restrict luxury vehicles from those under 25. UK drivers aren't legally required to have an International Driving Permit (IDP) to drive in the collectivity, unless you carry an older paper licence, or the rental company requests one.
Most roads in Saint Martin are paved, but many are narrow, winding and congested, especially near beaches, airports and resort areas. Traffic jams are common around Marigot, Simpson Bay and the Princess Juliana Airport, driving has often been described as a relaxed but chaotic experience that's heavily dependent on local courtesy, and with scooters and motorbikes weaving through traffic. With no formal border stop when crossing between St. Martin and Sint Maarten, be careful as you cross to the other side as both operate under distinct jurisdictions with differing enforcement styles and specific regulations.
When renting a vehicle, it is advised to choose a small car for easier parking and narrow roads, and to also inspect the vehicle carefully before driving away — taking photos of existing damage, and to confirm insurance coverage and cross-border permissions between French and Dutch sides. Additionally, avoid distracted driving as roads can change quickly, as well as night driving due to poor lighting and road markings, along with making sure to be careful when parking near beaches, and to not leave valuables visible in the vehicle.
Fuel stations in the collectivity usually have Sans Plomb 95 (unleaded petrol), Sans Plomb 98 (premium unleaded) and Gazole (diesel). During the day, many stations are attended, but some become self-service late at night. Some stations may reject foreign cards or require Chip-and-PIN at unattended pumps, so it is best to carry cash as backup. Despite prices in Euro, many stations accept US dollars, though often at a poor 1:1 exchange rate. Also, tipping is not required, though a small tip for helpful service is appreciated by some visitors.
Petrol stations are spread around the island and are rarely far apart, and several operate 24/7. But always make sure to not let your tank run too low. Some gas stations have air compressors that may not work properly. So if any punctures or tyre issues occur, don't rely on them in an emergency. Most rental cars use Sans Plomb 95 petrol, but always check the rental agreement, the fuel cap sticker or ask the rental company before driving away if that is the case for your rental. And before you return the vehicle, check the rental company’s fuel policy about what level of fuel the rental should return with (e.g. full-to-full), or face a high fee. Keep any fuel receipts and refuel close to the airport if required.
The legal limit is 0.05% across the entire island of Saint Martin.
Seat belts are mandatory for all passengers.
Children under 12 are strictly prohibited from riding in the front passenger seat, and children under 4 must be secured in a size- and weight-appropriate child restraint system.
