About 70 percent of the world drives on the right side of the road, while the remaining 30 percent stick to the left, largely due to British influence. But have you ever wondered why different countries chose opposite sides?
Well, the answer goes way back—long before cars even existed.
Why Americans Drive on the Right and the British on the Left
In the U.S., right-side driving can be traced back to the 1700s with Conestoga wagons. These massive wagons were essential for transporting goods and people, and their controls were positioned on the left. This setup made it easier for right-handed drivers to handle the horses, naturally leading to right-side travel.
When the Philadelphia and Lancaster Turnpike was built, it officially enforced right-side driving, setting a precedent. New York followed in 1804, and soon, the entire country adopted the rule.
On the other hand, Britain’s left-side driving tradition stems from horseback riding. Riders preferred to stay on the left to keep their dominant right hand free—whether to greet others or defend themselves in battle. This centuries-old practice carried over to cars when they hit the roads.
Countries That Drive on the Left
Britain’s left-side driving habit actually dates back to medieval times when knights and warriors kept their right hand free to wield a sword.
While Henry Ford’s Model T is often credited with influencing right-side driving in the U.S., the practice was already in place long before Ford’s cars became popular.
Japan also adopted left-side driving in the 19th century, influenced by British engineers who played a key role in building the country’s railway system. Other nations like India and Australia also follow the left-side rule due to British colonial influence.
Speaking of driving differences, have you ever wondered why Americans prefer automatic cars while the rest of the world mostly drives manual?
