Where should side markers be mounted on vehicles?

Side markers are designed to enhance the visibility of a vehicle from the side, particularly during low-light conditions or when merging into traffic. The appropriate placement of side markers is crucial for ensuring safety on the road. Mounting them as far to the front as practical allows for maximum visibility and helps other drivers to gauge the length and width of the vehicle. This positioning is especially important for larger vehicles, as it provides a clearer indication of their presence and dimensions, which can aid in preventing accidents.

Placement near the rear wheels or at the top of the vehicle does not fulfill the primary function of side markers effectively. Similarly, central placement would not provide adequate visibility to oncoming traffic from multiple angles. Hence, the specified location promotes better awareness and safety for both the driver and surrounding vehicles.
