If you have to drive on roads covered in snow, you should avoid...?

Answer: B — Sudden braking, sudden acceleration and sudden steering changes

Driving on snow-covered roads can be dangerous, and it requires caution and skill. Using your headlights, turning on the heating, and listening to the radio are actions that should be taken while driving, regardless of the road conditions. Choosing to avoid using these features would not increase safety on snow-covered roads. However, sudden braking, sudden acceleration, and sudden steering changes can cause the car to lose traction and make you lose control, increasing the chances of accidents. These actions should be avoided on snowy roads to ensure safe and smooth driving.
