It is not really black but rather clear. Black ice, sometimes called clear
ice, refers to a thin coating of glazed ice on a surface. The ice
itself is not black, but virtually transparent, allowing the often black
road below to be seen through it.
Winter brings many dangers for motorists, with one of the most threatening being slippery and hard-to-spot black ice. Black ice forms when the air is at 32 degrees or below at the surface and rain is falling, according to AccuWeather .
The ground temperature causes the precipitation to freeze upon
impact, thus creating ice. Sleet and the refreezing of snow or water can also
generate black ice.
This type of ice gets its name from its ability to blend in with its surroundings.
"It's called black ice because it tends to look like the rest of the pavement on the road, but it's actually clear," Lee said.
The complexion of black ice makes it extremely difficult to spot, but using a car thermometer as an initial gauge can be helpful in determining the road conditions. A car thermometer, like any digital thermometer, tries to find the air's ambient temperature. So, if a vehicle's thermometer is close to freezing, the car driver should be cautious on the roads.
As winter quickly approaches, cold weather comes with it. Rain, snow, sleet, and ice can make for unpleasant, and sometimes unexpected, driving conditions. Black ice is one effect of winter weather that makes for particularly hazardous roads. Read on to learn more about black ice and how to drive on it.
What Is Black Ice?
AAA offers the following tips for motorists who encounter black ice while driving:
Black ice is
nearly invisible, which is why it is one of the most dangerous road conditions
you might encounter. When water freezes on the road, the pavement appears wet,
but not necessarily icy. If your vehicle hits black ice, the car could start to
skid and slide since there is no traction between the tires and the ice. Black
ice is most likely to occur in early mornings, evenings, and nighttime
AAA offers the following tips for motorists who encounter black ice while driving:
- Be aware of and on the lookout for black ice. Pavement with black ice will be slightly darker and duller than the rest of the road surface; it commonly forms on highly shaded areas, infrequently traveled roads, bridges and overpasses.
- Use extreme caution on bridges and overpasses, which typically freeze first and melt last. Even if the roadway leading up to a bridge appears to be fine, use caution as the bridge itself could be covered in a sheet of ice.
- Never use cruise control.
- Avoid unnecessarily changing lanes, which increases your chances of hitting a patch of ice between lanes that could cause you to lose control of the vehicle.
- Drive, turn and brake slowly, adjusting speed to road conditions and leaving ample stopping room (three times more than usual) and watching for brake lights, fishtailing or sideways cars and emergency flashers.
- Avoid braking on ice. If you approach a patch of ice, try to brake in advance and control the skid by easing off the accelerator and steering in the direction you want the front of the car to go.
- If you have antilock brakes, do not pump the pedal; the vibrations and pulsating against your foot when you press down are the system working. For drivers without antilock brakes, use "threshold braking," keeping your heel on the floor and using the ball of your foot to apply firm, steady pressure on the pedal to the "threshold" of locking your brakes; removing your heel from the floor could cause your brakes to lock.
- Use your low-beam headlights.
- Remember, four-wheel drive doesn’t help you stop any faster.
- Keep a winter-weather kit in your car, containing an ice scraper, blanket, flashlight with extra batteries, bag of kitty litter, shovel and charged cell phone, as well as reflective triangles or flares, cloth or paper towels and jumper cables.
