How Many Countries Drive on the Right? Current List & Stats

Which countries drive on the right side?

North America

The majority of North American countries and territories follow right-hand traffic. This includes major nations like the United States, Canada, and Mexico, as well as Caribbean nations such as Cuba and Jamaica. The region adopted right-side driving in the early 20th century, influenced by automotive manufacturing trends and trade partnerships. Only Guatemala briefly experimented with left-side driving in the 1920s before reverting.

Most of Europe

Over 40 European countries drive on the right, including major economies like Germany, France, Spain, and Italy. This shift began in the late 18th century, notably under Napoleon Bonaparte, who mandated right-side traffic in territories he conquered. Exceptions include the United Kingdom, Ireland, and Malta, which retain left-hand traffic due to historical precedents.

Asia and Oceania

The majority of Asian countries drive on the right, such as Japan, South Korea, China, and Thailand. Notable exceptions include India, Indonesia, and Sri Lanka, which follow left-side traffic due to historical British influence. In Oceania, only Papua New Guinea and East Timor drive on the right, while Australia and New Zealand use left-hand traffic.

South America and the Caribbean

All South American countries, including Brazil, Argentina, and Colombia, drive on the right. This practice originated from 19th-century political shifts, with Brazil transitioning from left to right in 1945. In the Caribbean, nations like Haiti and Dominican Republic also adhere to right-side traffic, aligning with North American trade patterns.

Historically, the adoption of right-hand traffic expanded through colonial influence, industrialization, and post-WWII reforms. Countries like Japan switched to right-side driving in 1945 under U.S. occupation, while Sweden transitioned in 1967 to harmonize with neighboring nations. These shifts reflect global efforts to standardize traffic flow for safety and economic integration.

Why does Japan drive on left?

Historical Origins and Samurai Traditions

Japan has practiced left-hand traffic since at least the Edo period (1603–1868). Historical records suggest this tradition originated from practical reasons, such as the need for samurai warriors to keep their swords (worn on the left hip) accessible while passing others on narrow paths. Riding or walking on the left minimized the risk of sword-handling conflicts. This practice persisted long before automobiles existed, establishing left-side travel as a cultural norm.

Meiji Era Decisions and Modernization

During the Meiji Restoration (1868–1912), Japan modernized its infrastructure but debated adopting right-hand traffic, which was becoming standard in many Western countries. However, switching would have required costly reorganization of roads and public transport. Officials ultimately decided to retain left-hand traffic to preserve cultural continuity and avoid disruption. This choice solidified Japan’s adherence to left-side driving into the 20th century.

Post-WWII Considerations and the Occupation Era

After World War II, the U.S. occupation authorities (GHQ) briefly proposed switching to right-hand traffic to align with Allied nations. However, the Japanese government resisted, citing high implementation costs and public inconvenience. A 1950s survey even showed strong public opposition to changing. This resistance ensured Japan maintained its left-hand traffic system, a decision that persists today.

Key factors include historical tradition, infrastructure costs, and cultural identity. Japan’s unique blend of ancient practices and practical modern governance explains why it remains one of the few major nations outside the British colonial sphere to drive on the left.

Why does Canada drive on the right?

Historical Shift from British Tradition

Canada initially followed the British colonial tradition of driving on the left, a practice rooted in medieval military tactics and horse-and-carriage traffic. However, by the early 20th century, the United States’ influence became a key factor. As automobile imports from the U.S. (which drove on the right) surged, Canada gradually shifted to align with its southern neighbor. Ontario famously transitioned in 1922, and other provinces followed, prioritizing trade, infrastructure consistency, and safety. This shift mirrored global trends where many former British colonies, like Australia and India, retained left-hand driving, but Canada diverged due to its geographic and economic ties to the U.S.

Practical and Safety Considerations

Driving on the right became standard in North America for practical reasons. Most people are right-handed, and in horse-drawn carriage eras, riders preferred to sit on the left to hold reins with their dominant hand while using a whip with the right. By driving on the right, drivers could better monitor traffic and avoid collisions. Additionally, right-hand drive vehicles (common in the U.S.) were cheaper and more accessible, pushing Canada to adopt the same side to streamline cross-border travel and reduce accidents at shared borders.

Modern Alignment with Global Traffic Standards

Today, over 90% of the world drives on the right, including major trading partners like the U.S., Japan, and continental Europe. Canada’s adherence to right-side driving ensures seamless international trade routes, tourism, and vehicle compatibility. While some countries like the U.K. and Japan retain their historical practices, Canada’s choice reflects a balance between historical context, economic pragmatism, and safety. This alignment also simplifies licensing, traffic rules, and emergency response protocols across North America.

Why does Germany drive on the right?

Historical Roots and the Shift from Left to Right

For centuries, many regions, including parts of Europe, used the left-hand driving tradition, influenced by historical practices like horse-drawn traffic and sword-wielding riders. However, Germany shifted to driving on the right in the early 19th century. This change was largely driven by Napoleonic influence, as France (a right-hand driving country) occupied and reformed German territories. After Napoleon’s defeat, some German states retained the practice to align with France’s transportation systems, while others followed later. By 1871, when the German Empire was unified, right-hand traffic became standardized nationwide to streamline trade and military movements.

Railway Development and Traffic Regulations

The rise of railroads in the 19th century solidified Germany’s preference for the right. Early German railways adopted right-hand tracks to mirror practices in France and other continental neighbors. This infrastructure prioritization eventually trickled down to road traffic. In 1871, the Imperial Road Traffic Regulations formalized right-hand driving as mandatory, ensuring consistency across the newly unified empire. This decision also aimed to reduce collisions between horse-drawn wagons, as riders could more easily monitor oncoming traffic from the right side.

International Agreements and Modern Standards

Germany’s choice to drive on the right aligns with the majority of the world, including most of Europe and North America. This global trend was further cemented by the 1968 Vienna Convention on Road Traffic, which reinforced right-hand driving as the international standard. Today, Germany’s adherence to right-hand traffic ensures seamless cross-border travel, particularly within the EU, where 95% of countries follow the same rule. Only a handful of nations, like the UK and Japan, retain left-hand driving, rooted in their own historical contexts.
