In many countries around the world, vehicles drive on the right side of the road. This traffic arrangement is known as right-hand traffic (RHT), and it contrasts with left-hand traffic (LHT) systems used in other nations. The choice of which side of the road to drive on can significantly affect the road infrastructure, vehicle design, and traffic regulations.

Key Features of Right-Hand Traffic Systems:

  • Drivers sit on the left side of the vehicle.
  • Road signs are designed for the perspective of right-side driving.
  • Intersections and traffic signals are set up to accommodate RHT vehicles.

Historical Context:

Right-hand traffic systems were established in various countries for practical reasons, such as ease of vehicle control and historical development. The United States, for example, adopted RHT in the 18th century, which influenced the traffic norms in several other countries, especially those influenced by American automotive practices.

Right-hand traffic helps in organizing vehicle flow, enhancing safety, and reducing accidents in countries where it is implemented.
