You are driving at the 50 mph speed limit. It starts to rain quite heavily. Which of the following should you do?
The posted speed limit assumes safe driving conditions. When the road is wet, slow down to prevent skidding or hydroplaning. (New Jersey law requires you to slow down in hazardous driving conditions.) In poor weather, turn on your headlights to improve visibility. (New Jersey law requires you to turn on your headlights whenever you're using your windshield wipers.) Don't use cruise control on wet, icy, or snowy roads. If your vehicle loses traction on a slippery surface, the cruise control may spin the drive wheels as it tries to maintain a constant speed. This can worsen or even cause a skid.
