Where should you place your warning devices on a one-way road or divided highway?

When you are required to place warning devices on a one-way road or a divided highway, they need to be positioned to effectively alert approaching traffic of a hazard or breakdown. The correct placement is at distances of 10 feet, 100 feet, and 200 feet toward the direction from which traffic is coming.

This approach ensures that vehicles have ample time to see the warning devices and react appropriately to the situation. The initial placement at 10 feet is close enough for drivers to notice the obstruction without being dangerously close to the scene, while the placements at 100 and 200 feet provide increased visibility for drivers further away. This progressive distancing gives drivers enough time to slow down or change lanes safely.

The reason why this option is the one to choose is that it adheres to common safety practices established in driving regulations, ensuring maximum visibility and safety for both the drivers and those involved in the incident on the road.
