In earthquake season you also need nonperishable food, like trail mix and granola bars, water, scissors, pet food, a change of clothes and comfortable shoes. Duct-tape can also come in handy.

During the winter season you may need an ice scraper and brush, matches, a shovel, extra windshield washer fluid, and sand to sprinkle on icy patches for traction. If you do get stuck in drifting snow, keep snow and ice from blocking the exhaust pipe. Lower the car window slightly to avoid asphyxiating carbon monoxide fumes from entering the vehicle. Run the engine and heater about ten minutes an hour, but adjust this according to the amount of gasoline you have in your tank. Don’t leave the car unless you know your exact location and the time and distance required to get help.

Remember, you do not need to drive the speed limit. It takes three times longer/further to stop on a wet roadway than on dry. Visibility in tule fog can deteriorate at any moment to as little as 1/8 mile (660 feet) or less, according to CSAA. Avoid stopping on the traveled lane of any roadway.
