Fun Fact; Why Do the U.S. and Other Countries Drive on the Right Side of the Road?
Although the U.S. was colonized by Britain, people traveling on horseback and by wagon used the right side of the road, according to the Department of Transportation (DOT). By sitting to the left, drivers could better see oncoming travelers and defend themselves when necessary. When Pennsylvania began plans to build a turnpike in 1792, it adopted a law requiring drivers to use the right lane. Soon after, New York legally required drivers to use the right side of all public highways. Every state followed suit by the Civil War, the DOT says.
Right-side travel was further reinforced in 1908 when Henry Ford introduced his popular Model T with the steering wheel on the left side, National Geographic explains, and other auto manufacturers followed the trend. Over the years other countries also adopted right-side travel, often to help facilitate trips across their borders. Canada, for instance, switched from driving in the left lanes in favor of the right to allow easier travel to and from the U.S., the History Channel explains.
Although most countries adopted their respective sides of the roads decades ago, some have switched traffic patterns more recently. Samoa, which previously favored the right side of the road, moved to the left in 2009 to help drivers more easily travel in Australia and New Zealand, which drive on the left. It’s unlikely many other countries will make similar changes due to the costs of changing infrastructure
