If you think the road surface may be becoming icy, you can check for ice on your vehicle by opening the window and feeling the front of the side mirror, mirror support, or antenna. If ice has formed on any of these items, the road is likely becoming icy as well.

2. You can lower the risk of jackknifing by:

Over-accelerating.

Steering while braking.

Steering smoothly.

For leaks.

To ensure that they are still clear.
