Thailand has a reasonable network of roads and highways throughout the country, designated by numbers. Traffic in Bangkok drives on the left and the minimum driving age is 18 years. The speed limits are 60kph (37mph) in the city, 90kph (56mph) on main country roads and 120kph (74mph) on expressways. A national driving licence or International Driving Permit is required but long-term visitors staying over three months need to obtain a Thai driving licence.
Driving in Thailand is not for the faint-hearted as drivers tend to take risks and overtake on bends and hills, while buses and lorries drive as if they own the road. Driving at night is to be avoided as most heavy trucks travel at this time. The incidence of accidents is high and, when foreigners are involved in accidents, it is always assumed that it is they who are at fault and they are expected to pay the costs. Having said that, driving is the best way to see the countryside.
