Unless you are staying in Roseau or doing extensive guided tours, a car may be a necessity. Cabs can be very expensive. Daily car-rental rates begin at about $54 to $100 (weekly and long-term rates can be negotiated). A refundable US$1,200 deposit or credit card confirmation is required at the time of pickup. You'll need to buy a visitor's driving permit for $12 at one of the airports or at the Traffic Division office on High Street in Roseau or at vehicle-rental offices. Gasoline stations are all over the island; gas costs considerably more than in the United States. Driving in Dominica is on the left side, though you can rent vehicles with a steering wheel on either the left or the right.
