TV footage of the heavy snowfall down south included shots of 4WDs in ditches or slithering helplessly, visual proof that contrary to a widely held belief, having drive to all wheels isn't a magic carpet solution to all adverse driving conditions. 4WDs are subject to the same laws of physics as other vehicles; when there's no traction (friction), they aren't going to go anywhere. Chains, however, can make a big difference. In his excellent 2004 book, The New Zealand 4 Wheel Drive Handbook (ISBN 1-877251-24-0), Ken Sibly writes: "It goes without saying that if you are driving off-road in snow or icy conditions, chains should be fitted to at least the front wheels so that you steer the vehicle. A full set is preferable."
|Turning off onto the snow: chains not needed here, but it could get worse.|
