What is the purpose of a ‘warning triangle’ in a commercial vehicle?

The purpose of a warning triangle in a commercial vehicle is to alert other drivers of a stopped vehicle on the road. When a vehicle becomes disabled or needs to stop unexpectedly, placing a warning triangle behind the vehicle serves as a visual signal to oncoming traffic. This warning system is crucial for ensuring safety on the road, as it helps prevent accidents by giving other drivers a heads-up about the hazard ahead.

In situations where visibility is low or conditions are not ideal, such as at night or in poor weather, the warning triangle becomes even more vital. It is typically required by law for commercial vehicles to carry warning triangles, adding an additional layer of safety for both the stopped vehicle and other road users.
