Black ice fools drivers. Its shine tricks them into thinking it's water on the road. What they may not realize is that condensation, such as dew, freezes when temperatures reach 32 degrees or below. This forms an extra-thin layer of ice on the road. This shiny ice surface is one of the most slippery road conditions.
Black ice is likely to form first under bridges and overpasses, in shady spots and at intersections.
Road Tip Driving conservatively, keeping plenty of space between cars and allowing for longer stopping distances will help keep you driving straight on slick roads. Then steer in the direction you want your car to go. Before the rear wheels stop skidding, shift to drive and gently press the accelerator. Do not slam on the brakes.
