For reflectors to be compliant, they must be positioned at what range above the ground?

Answer: B — 24 to 60 inches

The correct range for positioning reflectors is 24 to 60 inches above the ground. This height range is important because it ensures that the reflectors are visible to other drivers, especially those in larger vehicles, and can effectively assist in safety during both daytime and nighttime conditions. Placing reflectors within this specified range helps to maximize their reflectivity and visibility, enabling them to better indicate the presence of a vehicle, particularly when parked or in low-light situations. Proper reflector height is part of compliance with safety regulations that aim to minimize accidents and improve overall road safety.
