Generally speaking, the whole road network on Reunion Island is well maintained, and well signposted. The highway code is similar to that in mainland France. Come and explore the ultimate island in a hire car. Every road is unique and surprisingly beautiful:
In the busy regions, between Saint-Denis and Saint-Gilles, in Saint-Pierre and Saint-Benoît, there is often a lot of traffic during rush hour (7am-9am), (4pm-6pm). Don’t forget to take a bottle of water with you, even more so if you have fragile people with you (young children, elderly people, etc.). Be careful while driving in the highlands, roads can sometimes be very winding and narrow, do not cross any flooded areas. Make sure you find out about any closed roads before setting off to the airport: traffic news. When driving around Reunion Island, Google Maps and Waze really come in handy.
Watch out for speed cameras !
