Commercial Driver’s License (CDL) Practice Exam

The primary function of reflective triangles for commercial vehicles is to alert other drivers to the presence of a stopped vehicle. These triangles are part of safety equipment that is required to be carried in commercial vehicles. When a vehicle becomes disabled or stops on the road, deploying these reflective triangles helps to increase visibility, especially in low-light conditions. This visibility serves to warn approaching drivers, allowing them to slow down and take appropriate action to avoid accidents.

By providing a clear visual signal, reflective triangles effectively communicate to oncoming traffic that there is a hazard ahead. This is crucial for ensuring the safety of both the stopped vehicle occupants and other motorists. In situations where visibility may be compromised, such as at night or in inclement weather, the bright colors and reflective surfaces of these triangles are designed to catch the eye and direct attention away from the hazard.
