How many rear-view mirrors are required on a motorcycle?

Motorcycles are required to have two rear-view mirrors in order to enhance the rider's visibility and safety on the road. This configuration allows the rider to have a broader field of vision, reducing blind spots and improving the ability to detect approaching vehicles from behind. The presence of two mirrors enables a more comprehensive awareness of surrounding traffic, which is vital for safe maneuvering, especially during lane changes and turns. While one mirror can provide some visibility, it is insufficient for ensuring complete awareness, necessitating the use of two mirrors as a standard requirement for motorcycles. Having fewer than two mirrors would compromise safety and is, therefore, not in compliance with regulations. More than two mirrors, while potentially increasing visibility, is not a requirement for motorcycle operation and can lead to unnecessary complexity and potential hazards.
