Cook Islands on a British Licence — No Side Switch, IDP Recommended

The Cook Islands are about as gentle an introduction to overseas driving as a British visitor will find — a handful of South Pacific islands where most of the action is on Rarotonga, and where one familiar habit carries straight over.

Can you drive in the Cook Islands on a UK licence?

Yes. Your British licence is accepted, and an International Driving Permit is recommended to carry with it; arrange it in the UK before you travel. Hire companies on Rarotonga and Aitutaki will confirm exactly what they want to see at pickup, but a UK licence, the IDP and your passport together cover you. Scooter and car hire are both common here, and the formalities are light.

The reassuring part: they drive on the left

Like the UK, the Cook Islands keep left. There is no reversed-roundabout confusion, no wrong-way reflex at junctions — the instinct you arrive with is the right one. That removes the main hazard British drivers face elsewhere and lets you settle in quickly.

What it is actually like

Rarotonga is genuinely simple to drive: a single sealed ring road loops the island, traffic is light, and distances are tiny. The realities to watch are not speed or congestion but the small-island ones — pedestrians and free-roaming dogs at the roadside, the occasional pot-hole, and roads that are quieter and darker at night than you might expect. Many visitors get around by scooter, so leave room and look twice. The capital is Avarua, and the emergency number is 112.

There isn’t reliable published data on the exact posted speed limits or a tourist drink-drive figure for the Cook Islands, so I won’t invent numbers — keep speeds modest, treat alcohol as zero before driving, and follow local signage. Confirm whether you need the IDP with the Driving Permit Checker, and if you are island-hopping onward, our driving guides index covers the rules country by country.
