The speed limit in Simpson Bay is generally 50 km/h (32 mph). As you drive around the island and drive from the Dutch side to the French side, you are likely to encounter some out-of-town roads where the speed limit is 80 km/h (50 mph). However, due to frequent traffic congestion, speeds might be much slower. Make sure to follow traffic patterns and exercise the St. Maarten courtesy while driving. Search rental cars on KAYAK
