What is the function of reflective triangles in emergency equipment?

Reflective triangles are an essential component of emergency equipment used by commercial drivers. Their primary function is to warn approaching vehicles of a potential hazard on the roadway, such as a disabled vehicle or an accident scene. By reflecting light from headlights, these triangles make the presence of the vehicle more visible, especially in low-light or nighttime conditions, therefore alerting other drivers to slow down or change lanes to avoid a collision.

The use of reflective triangles is mandated in many jurisdictions as a safety requirement. They should be placed at specific distances from the vehicle to give drivers ample time to react. This proactive warning system helps prevent further accidents and ensures the safety of both the driver and the approaching vehicles.

In contrast, while reflective triangles can create some visibility, they do not provide light themselves or stabilize the vehicle. Their role is primarily as a visual warning tool, which is crucial for maintaining safety on the road.
