Question

what is the most important driving technique to avoid crashes when driving in icy or snowy conditions? get off the highways as quickly as possible. engage 4 wheel drive on the vehicle. reduce speed and increase following distance

Explanation:

In icy or snowy conditions, reduced traction means longer stopping distances. Slowing down and increasing following distance gives more time to react and stop safely. Getting off highways isn't always possible or necessary, and 4 - wheel drive helps with traction but not stopping distance as much as speed reduction.

Answer:

Reduce speed and increase following distance
