How many red reflective triangles should a driver carry?

A driver should carry three red reflective triangles because these triangles are essential for road safety. The purpose of these triangles is to provide a warning to other drivers in case of a breakdown or emergency situation. Placing one triangle at the rear of the vehicle is mandatory to alert oncoming traffic, while the driver may place the second triangle in front of the vehicle and a third one further back on the road to create a visible warning zone. This setup increases visibility and allows other drivers ample time to adjust their speed or change lanes, thereby reducing the risk of accidents.

Having only one or two triangles would not provide adequate warning, as they could potentially create blind spots or fail to capture the attention of approaching vehicles. Therefore, carrying three is a standard safety requirement for commercial drivers, ensuring they are prepared for any roadside emergency.
