Taiwan’s road safety issues can, in part, be traced back to historical decisions made during the mid-20th century, specifically the 1946 shift to driving on the right side of the road. Before 1946, Taiwan drove on the left, following Japanese road rules from its colonial period (1895–1945). The abrupt change, implemented without comprehensive infrastructure adaptation or public acclimation, has had long-lasting implications for road safety. Examining the impact of this switch and comparing it to the potential benefits of driving on the left reveals critical insights into Taiwan’s traffic challenges.
One significant impact of the 1946 transition was the mismatch between Taiwan’s infrastructure and road-use patterns. Japan had designed Taiwan’s roads, urban layouts, and transit systems for left-side driving. The post-war switch to the right introduced inefficiencies and inconsistencies. Roads, intersections, and traffic systems were not immediately redesigned to suit right-side traffic, creating confusion and inefficiencies that persist in some forms even today. The legacy of this disruption contributes to Taiwan’s relatively high traffic fatality rates, as road design and usage patterns remain less intuitive and harmonized compared to systems that evolved organically around consistent driving norms.
Further, driving on the left is often considered safer, particularly for densely populated or high-traffic regions, due to cognitive and physiological factors. Most people are right-eye dominant, and driving on the left allows the dominant eye to have a better view of oncoming traffic, potentially reducing accidents during overtaking or at intersections. Additionally, roundabouts and intersections are generally more efficient and safer when designed for left-side traffic, as studies have shown fewer conflict points compared to right-side systems. For Taiwan, a return to left-side driving could align better with these safety benefits, especially in its densely packed cities and mountainous regions.
Another critical consideration is vehicle compatibility. Taiwan’s shift to right-side driving forced it to import vehicles designed for right-hand traffic systems, primarily from the United States and Europe. However, if Taiwan drove on the left, it could import Japan’s kei cars—small, lightweight, and highly efficient vehicles designed for Japan’s dense urban environments. Kei cars are ideally suited for Taiwan’s population density and narrow roads, offering better maneuverability and fuel efficiency. Moreover, these vehicles often come equipped with advanced safety features and are manufactured to high standards due to Japan’s rigorous automotive industry regulations.
Kei cars could address Taiwan’s traffic challenges by reducing congestion, improving fuel efficiency, and enhancing overall safety. Their smaller size and agility make them well-suited for urban driving, where road widths and parking availability are often constrained. Adopting a left-side driving system would facilitate easier access to this class of vehicles, as Japan predominantly manufactures kei cars for left-side traffic systems. Currently, the dominance of larger vehicles designed for right-hand traffic exacerbates congestion and contributes to higher emissions, further compounding Taiwan’s urban transportation challenges.
In conclusion, Taiwan’s 1946 decision to switch to right-side driving disrupted its transportation system in ways that continue to impact road safety. A hypothetical return to left-side driving could align with safer traffic patterns, better suit the nation’s infrastructure, and open the door to importing Japanese kei cars. These vehicles, tailored for densely populated regions, would bring practical and environmental benefits, addressing some of the most pressing challenges in Taiwan’s transportation landscape. Revisiting historical decisions like this could offer transformative opportunities for improving road safety and urban mobility.
