The most important rule of the road concerns which side to drive on. A large number of accidents in the world happen for this reason, with more and more people (choose) car hire as the way to drive in a foreign country. Famous actor Matthew Broderick (catch) up in a bad collision when he rented vehicle in Ireland because he forgot that they drive on the opposite side of the road.
Most areas of the world which (previous) were British colonies still drive on the left hand side of the road, Australia, India, and South Africa (include). Most European countries drive on the right hand side apart Cyprus, Ireland, Malta and the United Kingdom. Guyana is the only country in South America drives on the left.
Generally speaking, about two thirds of the countries in the world drive on the right such as, the USA, China and Russia. Canada used to drive on the left but changed to the right to make border crossings with the USA more (manage).
The (explain) for driving on different sides of the road is historical. British horse riders used to ride on the left hand side of the road, thus keeping their right arm free to offer greetings to (passer-by). But in the USA Teamsters decided to start driving on the right so that they could see the passing wheels of other wagons.
