Left- and right-hand traffic
Most countries that drive on the left-hand side are former British colonies. However, some other countries still chose the left-hand side of the road. These countries include: Japan, Thailand, Nepal, Bhutan, Mozambique, Suriname, East Timor, and Indonesia. Today, only four European countries drive on the left-hand, the United Kingdom, Ireland, Malta, and Cyprus, all of which are islands. There are several countries where their territories that exist outside the mainland drive on a different side from the mainland. One well-known example is that all of China drives on the right-hand except for its Special Administrative Regions Hong Kong and Macau, which drive on the left-hand.
