Get out of traffic.
The goal is to get out of the traffic flow without causing a collision. If your vehicle is disabled, that can be a monumental challenge. Be patient, make sure the path is clear and remember to signal.
Find a safe place to stop.
Try to park in an area with flat terrain away from traffic. If you need to change a tire or perform other repairs, make sure you have enough room to safely work. Turn on the emergency flashers. Set out flares or emergency reflectors.
Unless help is nearby, stay with your vehicle. Police or a tow truck are likely to come by. If you have a cell phone, call for help. Raising your hood or tying a cloth to the door handle signals other drivers that you need assistance.
