Historical Background

The practice of driving on the right side of the road in the United States can be traced back to colonial times. In the early days of settlement, most people traveled on foot or horseback, which meant they would naturally keep to the right side of the road to avoid collisions with oncoming traffic. This convention was also influenced by the British, who drove on the left side of the road.

During the late 18th century, as carriages and wagons became more common, the need for standardized road rules arose. In 1792, Pennsylvania became the first state to pass a law mandating right-side driving. Other states gradually followed suit, and by the early 20th century, driving on the right had become the norm across the country.

Influence of Henry Ford

Henry Ford, the founder of Ford Motor Company, played a significant role in solidifying the practice of driving on the right in the United States. In the early 1900s, Ford’s Model T revolutionized the automobile industry and became the first affordable car for the average American. The Model T was designed with left-hand drive, meaning the driver sat on the left side of the vehicle.

Ford’s decision to place the driver on the left side was influenced by several factors. Firstly, it allowed the driver to have a better view of the road ahead, particularly when passing oncoming traffic. Secondly, it made it easier for the driver to exit the vehicle onto the sidewalk rather than into the middle of the road. Lastly, it simplified the manufacturing process, as most roads in the United States already followed the right-side driving convention.

Standardization and Safety

As the automobile industry continued to grow, the need for standardized road rules and traffic regulations became increasingly important. In 1909, the first national road safety conference was held in the United States, which led to the establishment of the Manual on Uniform Traffic Control Devices (MUTCD) in 1935.

The MUTCD provided guidelines for traffic signs, signals, and road markings, aiming to enhance safety and reduce confusion for drivers. By this time, driving on the right had become deeply ingrained in American society, and changing to left-side driving would have been a massive undertaking.

Moreover, the majority of American vehicles were designed for right-side driving, with controls and visibility optimized for this configuration. Switching to left-side driving would have required significant modifications to existing vehicles and infrastructure, making it impractical and costly.

Today, driving on the right side of the road remains the standard in the United States, with only a few exceptions such as the U.S. Virgin Islands, where driving is on the left. The practice continues to be upheld to ensure consistency, safety, and compatibility with the majority of vehicles on American roads.


One unique perspective on why Americans drive on the right is the influence of the early settlers and their preference for keeping to the right side of the road to avoid collisions. This convention was further reinforced by the British, who drove on the left side of the road. Over time, as carriages and wagons became more common, standardized road rules were needed, leading to the adoption of right-side driving laws in various states.

Another innovative approach to this topic is the significant role played by Henry Ford and his Model T in solidifying the practice of driving on the right in the United States. Ford’s decision to design the Model T with left-hand drive was influenced by factors such as better visibility for the driver and easier access to the sidewalk when exiting the vehicle. Additionally, the existing right-side driving convention in the United States simplified the manufacturing process for Ford.

Furthermore, the need for standardized road rules and traffic regulations became increasingly important as the automobile industry grew. The establishment of the Manual on Uniform Traffic Control Devices (MUTCD) in 1935 aimed to enhance safety and reduce confusion for drivers. By this time, driving on the right had become deeply ingrained in American society, making a switch to left-side driving impractical and costly due to the significant modifications required for vehicles and infrastructure.

As a result, they adopted driving on the right side of the road, which was more aligned with their desire for independence and a break from British influence.

Case Study 2: Wagon Trails

Another factor contributing to Americans driving on the right is the influence of wagon trails. In the early days of road transportation, wagon trails were prevalent across the country. These trails were often narrow, and drivers preferred to sit on the left side of the wagon, allowing them to have a better view of the wheels and avoid obstacles. Consequently, driving on the right side of the road became the norm, as it allowed drivers to have better control over their wagons and navigate the trails more effectively.

Case Study 3: Henry Ford’s Influence

The introduction of the Model T by Henry Ford in the early 20th century also played a role in solidifying the practice of driving on the right in the United States. Ford’s Model T was one of the first mass-produced automobiles, and it was designed with the driver’s seat on the left side. This configuration allowed the driver to easily access the controls and have a clear view of the road ahead. As the Model T gained popularity, other manufacturers followed suit, and driving on the right side of the road became the standard in the American automotive industry.
