The preferred side for motorcyclists to drive on depends on the country or region in which they are riding. In the majority of countries around the world, including the United States, Canada, and European countries, motorcyclists drive on the right-hand side of the road. This is consistent with the general rule of driving on the right-hand side of the road in these countries.
On the other hand, there are a few countries, most notably the United Kingdom, Australia, Japan, India, and some African nations, where motorcyclists drive on the left-hand side of the road. This is because these countries have a historical tradition of left-hand traffic.
The choice of driving on the left or right side of the road is influenced by various factors, including historical reasons, conventions, and traffic regulations established by each country or region. It is important for motorcyclists to adhere to the driving rules and regulations of the specific country or region in which they are riding to ensure safety and maintain proper traffic flow.
