- If the vehicle has mechanical trouble, try to get the vehicle to a safe place out of traffic. Use 4-way flasher lights.
- If the vehicle must be stopped on a road or the shoulder of a road for more than 10 minutes, place reflective triangles at the following locations:
- On the traffic side of the vehicle, within ten feet of the drivers side rear corner, to mark the location of the vehicle.
- About 100 feet behind and ahead of the vehicle, on the shoulder or in the lane where the vehicle is stopped.
- Beyond any hill, curve or other obstruction that prevents other drivers from seeing the vehicle within 500 feet
- If vehicle is stopped on or by a one-way street or divided highway, place warning devices 10 feet, 100 feet and 200 feet toward the approaching traffic.
- When placing the triangles, the driver should hold them between him/herself and the oncoming traffic.
