Countries that Drive on the Left
About 35% of the world's countries drive on the left side of the road, a practice rooted in centuries of history. Most left-driving countries are former British colonies or territories with historical British influence, including the United Kingdom, Australia, Japan, India, and much of Southern and Eastern Africa. The convention dates back to medieval times when horse riders kept left to have their sword arm (usually the right) closer to oncoming traffic. Napoleon later enforced right-hand driving across his empire, which is why most of continental Europe drives on the right. Today, around 78 countries and territories drive on the left, home to roughly 2 billion people.
