In an emergency, a cellular phone and winter driving kit are invaluable. What to Watch Out For Many crashes occur under adverse driving conditions. Drivers can reduce the risks associated with driving on ice and snow by being aware of the amount of traction and adjusting vehicle speed and position to maximize visibility and increase time and space. Slow down before entering a curve. The reduced speed will allow for greater traction and control.
Vehicles starting and stopping at intersections can create a more slippery pavement.
This condition is more likely to occur at sunrise and sunset when temperatures change quickly. Air moving over and under the surface causes freezing to occur first on bridges, underpasses and overpasses. These surfaces may be slippery when the rest of the roadway is dry or wet. Black ice can form in shaded spots, and on underpasses and overpasses, creating a slippery surface that may be hard to see.
