How many red reflective triangles should be carried in your vehicle?

The correct answer is that a vehicle should carry three red reflective triangles. This is in line with Federal Motor Carrier Safety Administration (FMCSA) regulations, which require commercial vehicles to have these triangles as part of their emergency equipment.

The purpose of the red reflective triangles is to provide warning to other drivers when a vehicle is disabled or parked on the side of the road, particularly in low visibility conditions or at night. Having three triangles allows for placement in multiple locations, enhancing visibility and safety. For example, one triangle can be placed at the rear of the vehicle, while the others might be positioned further down the road to alert oncoming traffic. This strategic placement is crucial for alerting other drivers, thereby reducing the risk of collisions.

Carrying only one or two triangles would not provide sufficient warning, especially on roads with high-speed traffic, which is why three is the mandated quantity for safe operation. Having four or more would exceed the requirements without being necessary or practical for most purposes.
