Rental cars are authorized anywhere in St Maarten / St Martin, but don’t forget that here we drive on the right side of the road. Certain trails are not suitable for luxury cars and they should be avoided. If you really wish to explore off road trails you should consider renting an all-terrain vehicle or SUV.
St. Martin (French part of the island) does adhere to European rules, which means that seat belts are mandatory, as are car seats for children babies and young kids. Driving with your mobile phone in your hand or to your ear will also result in a hefty fine.
Always wear your seat belts, but be extra vigilant on the French side to avoid any interruptions by the French police.
