Inspect all belts, tire inflation, fluids, and maintenance items. If you are unsure, ask a professional mechanic to check your vehicle. If your oil pressure or water temperature light comes on, pull into a service station or other nearby location as quickly and safety as possible. A portable or cellular telephone is great to have while on the road. If your vehicle breaks down or a roadside emergency occurs, you will be able to notify the proper authorities.
Some people choose to carry pepper spray as a means of personal protection.
If you choose to carry it, be sure and keep it in a handy location. If it dangles from the end of your keys, it will do you no good if the keys are in the ignition. Before you leave on a trip, let someone know exactly when you are leaving, the route you plan on taking, and the time you expect to arrive. If you stop at a roadside convenience store for a short break, DO NOT leave the car running. Take your keys with you while you go inside the store.
