In the case of a breakdown on a divided highway, where should the three reflective triangles be placed?

The correct placement of reflective triangles in the event of a breakdown on a divided highway is critical for the safety of both the driver and other road users. The recommended distance of 10 ft, 100 ft, and 200 ft allows for optimal visibility, ensuring that vehicles approaching the scene have ample time to react and change lanes if necessary. This placement strategy is designed to alert drivers at varying distances, which is particularly important on faster-moving highways where reaction times are crucial.

The first triangle at 10 ft provides immediate warning to anyone approaching very closely, while the second triangle at 100 ft and the third at 200 ft allow for further distance warnings. This tiered approach increases the likelihood that drivers will see the warning signs before reaching the breakdown, facilitating safe maneuvering around the incident. Proper use of reflective triangles is part of safe roadside practices and helps prevent additional accidents in such situations.
