Where should reflectors be placed when stopped on a divided highway?

When a vehicle is stopped on a divided highway, reflectors or warning devices should be positioned at specified distances to alert oncoming traffic of the vehicle's presence and prevent potential accidents. Placing reflectors at intervals of 10, 100, and 200 feet behind the vehicle is designed to give adequate warning to approaching drivers, allowing them enough time to react and slow down safely. This spacing is crucial, especially on a divided highway where higher speeds are common, and visibility may be limited.

The selected distances provide a clear and effective warning system, ensuring that other drivers have sufficient notice to see the reflective devices in advance. The goal is to maximize safety by preventing collisions due to the sudden appearance of a stopped vehicle.
