Proper placement of emergency triangles behind a truck is crucial for road safety, especially during breakdowns or accidents. The general guideline is to place three reflective triangles at specific distances to alert oncoming traffic and prevent collisions.

The first triangle should be placed approximately 10 feet (3 meters) directly behind the truck. This alerts drivers immediately behind the vehicle. The second triangle should be placed 100 feet (30 meters) behind the truck to give vehicles approaching from farther away adequate warning. The third triangle should be placed 200 feet (60 meters) behind the truck, especially on high-speed roads, ensuring visibility for drivers at a greater distance.

On curves, hills, or blind spots, it’s essential to adjust triangle placement to provide enough warning before a vehicle can see the truck. By following these guidelines, truck drivers can help reduce accidents and increase the safety of everyone on the road.
