If you have to make an emergency stop on a road or highway, pull your vehicle completely off the traveled portion of the roadway. Then warn other road users. Turn on your hazard (four-way) flashers and raise the hood of your vehicle. Tie a piece of cloth to the driver's side door handle. If you have warning devices such as flares or reflective triangles, exit your vehicle on the passenger side and set them out on the ground, 200 to 300 feet behind your vehicle.
