Tick before you go
7 legal must-haves. Print it, tick them off, throw it in the glovebox.
Buy a local temporary driving permit
Visitors must purchase a Saint Lucia temporary driving permit (XCD 54 / about EUR 18, valid 3 months) from immigration, the police, or the car rental desk: your UK/EU licence alone is not enough to drive legally.
Full home driving licence + passport
Carry your full (not provisional) UK or EU photocard licence plus passport whenever driving; both are required to issue the temporary permit and at police checks.
Rental insurance / CDW
Third-party motor insurance is compulsory and is bundled into every rental; check the CDW excess (typically XCD 2,000-4,000 / EUR 680-1,360) and consider topping up: green card / UK personal motor insurance is not valid here.
Drive on the LEFT
Saint Lucia drives on the left like the UK, so most rentals are right-hand drive: comfortable for British drivers, a significant adjustment for continental EU visitors.
Speed limits 80 / 50 / 30 km/h
Maximum 80 km/h on the open Castries-Vieux Fort highway, 50 km/h on rural roads, and 30 km/h in towns and villages; limits are strictly enforced by radar near Castries and Rodney Bay.
Blood alcohol limit 0.08 g/dL
The legal BAC limit is 0.08 g/dL (80 mg/100 ml), the same as England, but given narrow, unlit mountain roads, plan on zero alcohol before driving.
Seatbelts and no handheld phones
Front-seat seatbelts are compulsory, handheld mobile phone use while driving is banned, and children under 5 must use a child seat; fines start around XCD 500 (EUR 170).

Saint Lucia recognises the 1949 Geneva IDP; it is not legally required if you obtain the local temporary permit, but carrying one smooths rental pickup and police stops.

Dial 999 or 911 for police, ambulance, or fire; response times outside the Castries-Rodney Bay corridor can be slow, so note your rental company's 24-hour assistance number before setting off.
Roads outside the highway are winding, single-lane in places, and badly potholed especially after rain: a small SUV or 4x4 is strongly advised for trips to Soufriere, the Pitons, or the rainforest interior.
Heavy tropical rain June-November causes landslides, flash floods, and road closures particularly on the west coast road; check conditions before crossing the island and avoid driving at night during storms.
There are no toll roads, motorway stickers, or electronic charging schemes anywhere on the island: all public roads are free to use.
Saint Lucia has no LEZ, ULEZ, or emissions sticker scheme; any roadworthy vehicle may enter Castries and other towns without registration.
There is no legal requirement to carry a hi-vis vest, warning triangle, or first aid kit, but a spare tyre in working order and a torch are sensible given remote stretches and frequent night-time power cuts.
Local currency is the Eastern Caribbean Dollar (XCD), pegged at roughly XCD 2.70 = USD 1 (about XCD 2.95 = EUR 1); US dollars are accepted almost everywhere, but pay fuel and small shops in XCD for the best rate.
Petrol costs roughly XCD 14-15 per imperial gallon (about EUR 1.10-1.25 per litre); most stations in Castries, Rodney Bay, and Vieux Fort take cards, but carry XCD cash for rural stations and tipping pump attendants is not expected.
