At what minimum height must mounted reflectors be placed from the ground?

Mounted reflectors should be placed at a minimum height of 24 inches from the ground to ensure they are visible and effective in guiding or warning drivers and pedestrians. This height promotes engagement with the reflector in a way that can be effectively seen from a distance, reducing the likelihood of obstructions such as vegetation or debris that might block lower-mounted reflectors. A height of 24 inches also aligns with standard safety and visibility regulations, making sure that they are easily noticeable while maintaining an appropriate height for vehicle dynamics.

In contrast, choosing a height that is significantly lower may lead to inadequate visibility, which can compromise safety measures on the road. Reflectors placed too low could also be subjected to damage from vehicles or pedestrian traffic, reducing their functionality over time. Hence, establishing the minimum height at 24 inches is a thoughtful balance between visibility, effectiveness, and safety in traffic management.
