So why do Brits drive on the wrong side of the road?

Brits aren’t the only ones who use this long-lived road practice of driving on the left side. About 60 countries around the world — many of them former British colonies — drive on the left, according to

The origin of traveling on the left side dates back before the invention of the automobile to the horse-and-buggy days.

This rule of the road possibly came about as a result of violent feudal societies. Since most people were right-handed, traveling on the left was a wise tactic to protect one’s self with a weapon in their dominant hand, according to

Famed conqueror Napoleon Bonaparte overturned this practice as part of a social rethink during revolutionary France, the Web site said. This could have been because Napoleon was left-handed, and he made his armies march to the right so he could keep his sword between him and the advancing enemy, the Web site added.

A newly formed United States changed its traffic system to the right side as well, according to, as a way to sever ties to its British colonial past.

And since the U.S. eventually climbed to the top of the automotive trade at one time, more and more American-style vehicles littered the world, prompting many other countries to alter their traffic systems, the Web site said.
