If you think the road surface may be becoming icy but you are not certain, you can open your window and feel 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.

Roads are particularly slippery when it first begins to rain. The water mixes with oil drippings on the road that have not yet washed away, creating a slippery and dangerous mixture.

The securement of cargo must be checked within the first 50 miles of a trip, and then again every three hours or 150 miles.
