Before heading out, its a good idea to check your local weather forecast along with weather conditions in the place you will be going. Checking routes to see if they are open or closed and following detour routes help keep you safe from getting stranded or driving in hazardous conditions. Unless you must travel, stay home until conditions improve.
If driving, keep your gas tank at least half full in the winter to prevent freezing of the gas line. Check all of your car's fluids before the trip to make sure they are optimum. Make sure the tire pressures are set to the recommended psi and have good treads. Clear off snow from windshields, lights and license plates and keep a scraper and brush in the car. Dress in layers to keep warm if you would get stranded. And have an emergency kit in your vehicle at all times. The kit should include a flash light with extra batteries, first aid kit, warm blanket, cell phone charger, jumper cables, reflective warning triangles, and a piece of bright clothing to put in the side window for others to see your vehicle. You should also have some non perishable food and water. Keep a small shovel and kitty litter or bag of sand in the trunk. But don't over exert yourself if you need to shovel out.
If you are stranded during heavy snow or conditions of reduced visibility, it is recommended to not leave your car. Make sure your exhaust pipe is clear of snow and only run the engine for short intervals to help get some heat, and crack the window to prevent carbon monoxide build up. Many insurance carriers, car manufacturers and AAA provide roadside assistance. Have their contact information handy in your vehicle.
When driving in snow, slow your speed, remember to keep your distance between the car ahead of you, follow at least 200 ft behind a snow plow or salt truck. Don't brake suddenly, avoid using cruise control, and get a bit of inertia when going up a hill and don't stop on the hill to avoid getting stuck. And have your headlights on for visibility.
If planning a trip via plane, train, or bus, always check with your airline or carrier before you leave to see any cancellations or delays. If possible, book a hotel near the airport the day before your travel to get ahead of worrisome weather. Today most companies will contact you in advance with any travel related information.
Whether you are going out to the local store, or going on vacation, use good judgement, be safe and prepare in case winter weather disrupts your plans.
