On a one-way, divided highway, where should the emergency warning signs be placed?

The correct placement of emergency warning signs on a one-way, divided highway is crucial for ensuring safety and providing adequate notice to approaching drivers. The specified distances in the correct answer indicate that emergency warning signs should be placed at various intervals to warn vehicles effectively before they reach the emergency situation.

By placing a warning sign 10 feet behind the vehicle, it gives immediate awareness to upcoming traffic in close proximity. The additional placements at 100 feet and 200 feet allow for longer-range visibility, which is essential for drivers traveling at higher speeds typically found on highways. This strategy helps to prevent accidents by giving drivers ample time to react and make decisions when they see the signs.

These distances align with standard safety protocols for warning sign placement, ensuring that they are visible and actionable in various traffic conditions.
