Allow 15-30 extra minutes for travel and ten extra minutes to get the snow off your car. Make sure to clean all the ice and snow off your car. If you leave it on the hood, it will make a whiteout for you. If you leave it on the roof or trunk, it will make a whiteout for someone behind you. If you leave it on the lights, others will not be able to see your vehicle at a distance. If you leave it on the mirrors, you will lose two fields of vision. Turn the front and rear defrosters and the headlights on when you start the car. The heat makes cleaning them easier. Leave the defrosters on to keep the front and rear windows from refreezing and use the wipers and washers as necessary. Use low beams because the high beams will reflect off the snow and make a glare. Make sure your tires have adequate tread and are inflated evenly. If one is low, the car will pull in that direction and your car will spin when it shouldn't. Make sure the washer fluid is filled and not frozen. It helps in general to have plenty of gas, warm clothes, and emergency supplies at all times.
Your first challenge when getting on the road may be getting out of your parking space. If the snow is piled up or frozen around your car, then you may have to rock it forward and back by rapidly switching from reverse to drive and giving it a little gas. If it doesn't work in a few seconds, stop as this maneuver heats up the transmission so much that sometimes a vehicle can catch fire. If you do find yourself stuck at any point, you can put the floor mats under the tires to get traction. This applies to the drive tires, so know if your vehicle is front wheel or rear wheel drive. If you carry sandbags for weight, you can open one of them and spread the sand for traction. Start moving slowly, as torque is greater at lower speeds. Gradually increase your speed to a safe speed, enough to keep your vehicle moving but not so fast you lose control. Allow more room between your vehicle and those around you. If someone else runs off the road ahead of you, don't follow their tracks as their sliding creates instant ice that will pull your vehicle right into theirs. But do not sharply turn the wheel. Steer slowly and in small increments. If you start sliding, steer into the skid. Don't try to correct by turning the wheel the opposite way. For example, if your car is sliding to the right, turn the wheel right to keep the car moving forward in a straight line. Yes, this is drifting! Feel for the traction and steering to return and gradually straighten the wheel. If you have to slow down and start sliding forward, you can regain traction by letting off the brake and slightly accelerating, but that eats up the distance you have to stop. That's why you have to leave extra room. If you have not practiced these maneuvers, try them in an empty, flat, snow covered parking lot. If you find yourself behind a plow truck, stay well back and follow it as long as you can to take advantage of the freshly cleared road. Do not pass plow trucks.
