How far should the second safety triangle be placed behind a vehicle on a two-lane roadway?

The second safety triangle should be placed 100 feet behind a vehicle on a two-lane roadway to provide adequate warning to oncoming traffic. This distance is established to ensure that approaching drivers have enough time to react to the presence of a stopped vehicle, particularly in situations where the speed limit may be higher or visibility may be reduced.

By placing the safety triangle at this distance, it helps to create a safe buffer zone around the stopped vehicle. This is particularly important in emergency situations or when the vehicle has broken down, as it alerts other drivers of potential hazards ahead, allowing them to slow down and navigate safely around the obstruction. Additionally, placing the triangle too close may not provide sufficient warning, while placing it too far could confuse drivers about the nature of the hazard.

Understanding the placement of safety triangles is crucial for maintaining safety on the road, and ensuring that the guidelines for distance are followed can significantly reduce the risk of accidents in such scenarios.
