How many safety triangles are required in a truck?

The correct answer is three safety triangles, which is a requirement for commercial vehicles, including trucks. These triangles serve as warning devices that can be placed on the road to alert other drivers in case of a breakdown or emergency situation. The Federal Motor Carrier Safety Administration (FMCSA) regulations specify that commercial vehicles must carry three reflective triangles. This allows for effective placement at different distances behind the disabled vehicle, which enhances visibility and gives approaching drivers adequate warning to reduce speed and maneuver safely around the obstacle.

Having only two would not provide enough coverage for warning approaching traffic, while four or five would exceed the requirement. Therefore, the appropriate number of safety triangles to carry in a truck is three, ensuring compliance with safety regulations and promoting safer road conditions.
