Weather, Visibility & EmergenciesStandalone practice
You are driving on a rural highway at 55 mph with cruise control on. Freezing drizzle starts, and the road surface begins to look wet and shiny. What should you do?
Correct answer: Turn off cruise control, slow down with your own foot on the pedals, and leave more space ahead.
Why
Freezing drizzle can cover the road with a thin layer of ice that is hard to see. Cruise control adds power to hold its set speed, and on ice that power can spin the drive wheels or push the car into a slide before you react. Keep full control of the speed yourself, drive slower and increase your following distance. Use cruise control again only when the road is dry.
