Traffic drives on the left. Most roads are tarred, with a 56kph (35mph) speed limit in built-up areas and 75kph (45mph) outside towns. Sri Lankan roads are generally narrow and inadequately maintained. Flashing lights mean that the driver is asserting right of way. Avoid remote areas and travelling at night.
In order to avoid bureaucratic formalities in Sri Lanka, an International Driving Permit should be obtained before departure. If not, a temporary licence to drive is obtainable on presentation of a valid national driving licence. This must be endorsed at the AA office in Colombo. The minimum age for driving a car is 18.
