One mistake that drivers make - especially the green ones - is to assume that since their four wheel drive vehicle can go, that it can also stop on snow or ice. But when it comes to stopping in wintry conditions, a four wheel drive can be just as much of a two ton "pig on ice" as any other vehicle. Why? Because, if all four wheels are on slippery ice, for example, what's going to help the vehicle when you hit the brakes? It doesn't matter if it's four wheels or two, it's still just rubber on ice. And that combination can mean sliding out of control. Again, this is why some owners of four wheel drive cars, trucks, and SUV's put chains on all four tires in the winter time.
So, if you're the proud owner of a four wheeler, keep in mind that your vehicle does have the advantage of having power to all four wheels. This can provide better traction when you are driving in the snow. This is probably the biggest reason that you decided to purchase this type of vehicle.
But, you must also keep in mind that your four wheel power isn't going to provide any better stopping traction than a two wheeler has. Therefore, you should always drive carefully in the wintry weather in order to avoid having an accident.
