If you must stop on a hill in a two-way road, how far back should you place your reflective triangles?

When stopping on a hill in a two-way road, it is important to properly place reflective triangles to ensure that other drivers can see the stopped vehicle from a sufficient distance, thereby enhancing safety. The correct answer indicates placing the triangles within 500 feet behind the vehicle.

This distance is crucial on a hill because it provides ample warning to approaching vehicles that may not have a clear line of sight to the stopped vehicle until they are quite close. On an incline, the elevation can obstruct a driver's view, and placing triangles too close could result in a collision if another vehicle cannot see your vehicle in time to react appropriately. By placing the reflective triangles far enough back, it gives approaching drivers time to slow down and adjust their path.

In addition, the 500-foot guideline is consistent with the general requirement for placing warning devices when stopped on any roadways to ensure maximum visibility and safety. Overall, the choice of this distance is designed to prevent accidents and protect both the stopped vehicle and oncoming traffic.
