Bad-weather practice →Separate starting traction from stopping space
Four driven wheels can create a misleading feeling of security. The handbook warns that four-wheel traction does not let the vehicle stop more quickly on a slippery road. Easy acceleration is not a test of braking grip.
Use gentle control inputs and allow more trip time. The posted limit does not tell you what speed suits the next shaded bridge or icy section.

Black ice is a thin, hard-to-see layer. Condensation on shaded highway sections, bridges and overpasses can freeze before the rest of the road; those places also take longer to thaw.
Clear the windshield and windows, and keep headlights, wipers and defrosters working. The handbook recommends winter tires on all wheels for winter traction. Equipment preparation complements a slower, more cautious trip.

Original learning cases
An AWD vehicle pulls away easily, then approaches a shaded bridge. That acceleration does not prove that the bridge offers enough grip for an ordinary stop.
Most of the road has thawed, but an overpass remains shaded. Expect a different surface instead of assuming the whole route has equal traction.
The defroster does not clear the windshield. Resolve the visibility problem before the trip rather than relying on the tires to compensate.
Plan before poor grip becomes an emergency
Check the weather and consider whether the trip should wait. Keep additional time and space for stopping. Follow the vehicle’s instructions for its braking system; this page does not give a universal skid-recovery drill or a guaranteed stopping distance.
