What is the required distance for flags, lamps, or flares during an emergency on a two-way road?

The correct answer specifies that flags, lamps, or flares must be placed at 10 and 100 feet behind the vehicle and 100 feet in front on a two-way road during an emergency situation. This guideline is designed to ensure adequate visibility and safety for other drivers approaching the scene. The distance behind the vehicle helps warn oncoming traffic of a potential hazard, giving them enough time to react and change lanes if necessary. The distance in front of the vehicle serves the same purpose, allowing drivers to notice the warning devices well in advance and avoid an accident.

Setting these distances is crucial for minimizing the risk of further collisions, especially on busy roads. The requirement of 10 feet behind ensures that the warning is not too close to the stationary vehicle, which could confuse oncoming traffic about the nature of the emergency. Additionally, having the flares or flags at a distance of 100 feet ensures that drivers have ample time to assess the situation and make safe driving decisions as they approach the warning signs.
