How far should a light be located above the surface of roads less than 40 feet wide?

Placing lights at an appropriate height above the surface of roads is crucial for ensuring adequate visibility and safety for drivers and pedestrians. The guideline for lighting above roads less than 40 feet wide typically recommends a height that allows for effective illumination without obstructing the view or causing glare.

A height range of 0 to 6 feet is suitable as it balances the need to provide sufficient light coverage while remaining low enough to avoid being too high, which could reduce the effectiveness of the lighting and create shadows. It allows for the light to be directed toward the roadway, improving visibility for those traveling on the road.

This height range also considers the types of vehicles that may be on the road, ensuring that the light can effectively illuminate the area without interference. In many contexts, keeping the lights within this specified range helps to enhance safety by providing uniform lighting that can minimize accidents and improve overall traffic conditions.
