When disabled on a divided highway, how far must one warning light be placed from the disabled vehicle?

The correct distance for placing a warning light from a disabled vehicle on a divided highway is 10 feet. This specific distance is crucial for ensuring the safety of both the driver of the disabled vehicle and other motorists on the road. By placing the warning light at this distance, it provides adequate warning to approaching drivers that there is a potential hazard ahead, allowing them to react appropriately and maintain a safe distance.

The choice of 10 feet strikes a balance between being close enough for visibility but far enough away to minimize the risk of collision with oncoming traffic. This is especially important on high-speed divided highways where visibility can be reduced and reaction time for drivers may be limited.

The other distances provided in the options are either too short or excessively far. A distance of 5 feet would not provide sufficient warning given the higher speeds and potential blind spots on highways, while distances of 100 feet or 200 feet may be overly cautionary, leading to decreased effectiveness of the warning signal. Thus, 10 feet is the appropriate safety standard as outlined in traffic regulations for managing such situations.
