Thailand drives on the left side of the road primarily due to historical influences. The practice of driving on the left dates back to the early 20th century when Thailand, then known as Siam, was modernizing its infrastructure. During this period, the country was heavily influenced by British advisors and engineers who were instrumental in developing Thailand’s road and railway systems.
Since the British drove on the left, they implemented the same system in Thailand. This decision was further reinforced when Thailand adopted the British model for its railway system, which also operates on the left. Over time, driving on the left became the standard practice throughout the country.
Another factor that contributed to this practice is the influence of neighboring countries. Many of Thailand’s neighbors, such as Malaysia and Myanmar, also drive on the left, making it a regional norm. This consistency helps facilitate cross-border travel and trade.
In summary, Thailand drives on the left side of the road due to historical British influence and regional consistency with neighboring countries. This practice has been maintained over the years and remains the standard in Thailand today.
