Why Do Some Countries Drive on the Left Side of the Road?

If you live in the United States, Canada, or most of Europe, cars drive on the right side of the road. But in places like the United Kingdom, Japan, Australia, and India, everyone drives on the left side instead. Have you ever wondered why?

The story goes back hundreds of years, long before cars were invented. In medieval times, most people were right-handed. When they traveled on horseback or walked along roads, they kept to the left side. This way, their right hand was free to greet friends or defend themselves with a sword if needed.

In the late 1700s, things started to change in some countries. In America and France, teamsters driving big wagons pulled by several horses liked to sit on the left rear horse. This gave them a better view of passing traffic if they kept to the right side of the road. The right-side habit spread to many countries.

Britain and its colonies kept the left-side tradition. When cars were invented, each country simply continued its old custom. Today, about 70 countries drive on the left, while most of the world drives on the right.

Some countries have even switched sides over the years. Sweden changed from left to right in 1967. It was confusing at first, but everyone adjusted. Whether left or right, the most important thing is that everyone in the same country follows the same rules to stay safe.
