There are 77 countries and regions where vehicles drive on the left side of the road, including Japan, the United Kingdom, Ireland, Australia, New Zealand, India, Indonesia, Pakistan, Thailand, South Africa, Sri Lanka, Malta, Papua New Guinea, Fiji, Tonga, Nauru, Jamaica, Malaysia, Singapore, South Africa, The Gambia, Sierra Leone, Ghana, Nigeria, the Bahamas, the Cayman Islands, the Turks and Caicos Islands, the British Virgin Islands, and others, primarily Commonwealth nations. Advantages of Left-Hand Traffic: The greatest advantage of left-hand traffic is its potential to reduce traffic accident fatality rates, primarily due to two reasons. First: Humans have an innate instinct to avoid harm. When moving at high speeds and encountering danger ahead, people instinctively lean or steer to the left. This allows them to use their right hand (typically the dominant hand) to protect their body and safeguard the left side of the chest where the heart is located. Second: Most people are right-handed. In a sudden hazardous situation while driving, the action of steering left (toward the curb) with the right hand is more forceful and quicker than steering right (toward the center of the road) with the left hand. This is particularly effective in avoiding head-on collisions when vehicles are approaching from opposite directions. Advantages of Right-Hand Traffic: The main advantage of right-hand traffic is that drivers can maintain control of the steering wheel with their left hand while using their right hand to perform complex actions such as gear shifting and operating the dashboard, which benefits right-handed drivers. Additionally, right-hand traffic makes it easier for cyclists or motorcyclists to signal turns with their left hand.

I have researched car driving habits, and countries that drive on the left mainly stem from historical traditions and colonial influences. For example, in the 18th century, British knights held swords in their right hands, making it safer to ride on the left side, which spread to many former British colonies. Today, key representatives of left-hand driving include the UK, India, Australia, New Zealand, South Africa, and Japan. Japan adopted the British system in the 19th century and has maintained it firmly to this day. Other examples include Thailand, Malaysia, Singapore, and parts of Indonesia in Southeast Asia; Kenya and Tanzania in Africa; and Caribbean nations like Jamaica. These regions account for about one-third of the world's countries, where turn signals and seat designs differ. It is advisable to familiarize yourself with local rules before traveling to avoid accidents.

There are many countries around the world where vehicles drive on the left side of the road. For instance, in Europe, the UK and Ireland stand out, while in Asia, Japan, India, Sri Lanka, Pakistan, and Bangladesh follow this practice. In Oceania, Australia and New Zealand are also common examples. In Africa, South Africa, Kenya, and Zimbabwe drive on the left, and in Southeast Asia, Thailand, Malaysia, and Singapore uniformly adhere to left-side driving. Most of these countries were historically influenced by British rule, featuring right-hand drive vehicles and different rules for turning priority. When traveling from right-driving regions like North America or parts of Europe and renting a car in these left-driving destinations, it's easy to accidentally enter the wrong lane. I use navigation reminders to gradually adapt for safer driving.

During my self-drive trip in Australia, I personally experienced left-hand driving, which left a deep impression! Under the British system, countries like India, Japan, South Africa, and New Zealand also drive this way, with the driver's seat mostly on the right side, and left turns being similar to right turns in right-hand driving countries. It was quite nerve-wracking at first attempt, but local rules are clear and accident rates are low. I recommend drivers practice in advance, and setting the GPS to the correct mode makes it much easier.
