1 . When making a turn, when should you cancel your turn signal?
It does not matter.
When turning or changing lanes, you should signal early and signal continuously. Cancel your turn signal once the turn or lane change is complete.
2 . If you see lights ahead while driving in fog:
The lights may not indicate where the road is as the vehicle may have pulled off the roadway.

3 . On slippery roads, you should:
Accelerate and decelerate frequently.
Make sure to drive slowly and smoothly on slippery roads. Do not pass slower vehicles unless it is necessary to do so. Avoid frequently changing your speed under such conditions.

Downshift.
Always downshift before entering a curve. Decreasing your speed before entering the curve will allow you to maintain better control over the vehicle throughout the curve.
