Grenada on a British Licence — Same Side, IDP Recommended, Dial 911

Grenada is small, green and mountainous, and a hire car is the easy way to reach its waterfalls and remote beaches. For a British visitor the fundamentals match home closely, which makes the island one of the gentler Caribbean introductions to driving abroad.

The verdict for British licence holders

You can drive in Grenada on your British licence, with an International Driving Permit recommended to carry alongside it. The IDP is cheap to arrange at a UK post office before you travel and is the sort of document rental desks prefer to see. One Caribbean habit worth knowing: visitors are often asked to buy a local temporary driving permit when they collect the car — ask at the rental desk whether it applies, rather than assuming, so there are no surprises.

Same side as home — and a hillier road

The useful fact for a UK driver is that Grenada drives on the left, exactly like the United Kingdom. There is no side switch to relearn and no junction reorientation to worry about. What does demand respect is the terrain: this is a volcanic island, so roads climb and twist steeply, lanes narrow without warning, and drainage gullies run close to the edge. Add frequent tropical downpours that turn surfaces slick in seconds, and the result is a place where your speed needs to drop well below anything a UK A-road would suggest. Use your horn lightly on blind bends as locals do.

What is different from home

The drink-drive limit is 0.08, the same headline figure as England, but Grenada’s unlit, winding rural roads after dark leave no room for error, so keep alcohol and driving apart. The emergency number is 911, not 999 — save it before you set off, as mobile signal fades in the mountainous interior.
