Question 8138

There is snow on the roadway. When is it required to use tire chains?

  1. Whenever the vehicle's tires do not grip the roadway well.
  2. Whenever the temperature is below zero degrees (0°).
  3. Whenever it is snowing.
Show answer and explanation

Correct answer: Whenever the vehicle's tires do not grip the roadway well.

You must fit chains when your tires do not grip the snow well, and whenever sign or a traffic officer requires them. Snow falling or the temperature dropping below zero is not enough on its own. Some winter tires can be used instead of chains.
