How many reflective triangles are required to have on a commercial vehicle?

Commercial vehicles are required to carry three reflective triangles as part of the safety equipment mandated by federal regulations. These triangles serve as a critical safety measure, providing visibility to warn oncoming traffic in the event of a breakdown or emergency situation.

Having three triangles allows for proper placement on roadways, ensuring that drivers can effectively signal their presence from various distances. One triangle can be placed a safe distance behind the vehicle to alert oncoming traffic, while the other two can be set out to increase visibility and to create a clear warning area. This is especially important on highways or in low-light conditions, where visibility is reduced.

While fewer triangles might not be adequate for ensuring visibility, having more than three is unnecessary and does not provide additional safety benefits. Therefore, three is the optimal number to comply with safety regulations and enhance roadside safety for both the driver and other road users.
