Reflective triangles are designed to be set up on the side of the road to alert oncoming traffic when you have made an unexpected stop on the side of a highway. Your stop may be the result of a flat tire, a breakdown or a personal emergency. By turning on the four-way blinkers on your car and using reflective triangles, you greatly reduce the risk of a minor occurrence turning into a tragedy if an oncoming driver doesn't see you.
Remove the reflective triangle from its plastic case. The triangle consists of three pieces that are folded together into a single cylinder.
Open up the three pieces and arrange them in the shape of a triangle. Attach the two free ends by snapping them together. Extend the stabilizing leg or legs that allow the triangle to stand upright.
Walk down the road in the direction from which traffic is coming. Set a triangle in the breakdown lane so that its reflective side is facing oncoming traffic. Don't put the triangle in the traffic lane. Set a triangle at least 250 feet behind your car so motorists will have time to see it and slow down. For extra safety, set several more triangles between the first one and your car.
