Before you actually use your kit in an emergency situation, take some time to familiarize yourself with the items you've collected and how to use them properly. Also remember that the most important thing is to exercise good judgment. If your car breaks down, make sure you stop on the shoulder, well out of the flow of traffic. Turn on your emergency flashers and, if you have roadside assistance and a cell phone, stay in your vehicle until help arrives. If it's a problem that needs quick response, or you are on that lonely country road, take out your emergency kit and proceed cautiously.
