Keep in mind bridges will accumulate snow before other parts of the road.
If you are driving in traffic, give yourself plenty of stopping distance.
If you are driving in the city, slow down approaching intersections and be prepared to slowly come to a stop in case a light turns red.
Remember, 4x4 or AWD does not apply to your brakes. You have the same brakes as a 2WD version of your car and they cannot stop any better in snow.
If you begin to slide and you have ABS, apply moderate pressure on the brake pedal. A pulsating feel is normal, it means the ABS is working.
If you begin to slide and you do not have ABS, pump the brake pedal.
Even with these techniques, your car may not stop in time, but they can slow it down to lessen damage and injury.
If you need to swerve, do not touch the brake pedal, that will cause your wheels to lock (even with ABS, it will lock in short bursts) and you car will not turn with the wheels locked.
If you have FWD, AWD or 4x4 and you need to swerve, you can apply slight pressure on the accelerator pedal to prevent the front wheels from locking and help turn the vehicle.
If you begin to skid, do not hit the brakes. Turn into the skid and slowly turn back towards the center of the road (as if you meant to drive onto the edge of the road and drive back).
Always keep an eye out for other motorist who may not be in control of their vehicles and be prepared to stop, accelerate or swerve to avoid getting hit.
If you have RWD (and to some extent, 4x4), you will want weight in the back end of your vehicle. This is easier with a pickup, because just about anything will work. For a car or SUV, bags of sand are a great idea because the sand is contained and you can use the sand, if you get stuck, to gain traction.
If you have snow tires, put them on.
Always carry an emergency kit including blanket, flashlight, flares, water, and anything else you may need to spend a few cold hours in your car.
Have a lot of patience, be smart and be prepared for the worst.
