With freezing temps
What is black ice?

As cold air moves in behind the wintry storms, this guarantees there will be black ice, especially on untreated surfaces.

Black ice isn’t black. It’s regular ice that is transparent and when it forms on pavement, drivers cannot see it as it blends in with the pavement. This is what makes black ice so dangerous for drivers and it can easily catch them off guard.

Black ice is most likely to form when air temperatures are at their lowest, either at or below freezing. Black ice usually forms after dark or in the early morning when little sunlight melts the ice. It will have a glossy appearance on the roadway.

One main area to be on the lookout for is a shady area. These areas that don’t receive sunlight until later in the morning or even the afternoon, where temperatures are still at or below freezing, can still have black ice on them. Additionally, bridges are the main area where black ice will likely form first. Since the roadway's top and underside are exposed to the freezing or sub-freezing air, ice forms here quickly.

If the forecast calls for cold air to move in, especially after rain, drive with the expectation of black ice on the roadways and keep a safe distance between you and the vehicles ahead in case they encounter the slippery surface first.

If you encounter black ice, stay calm and do not hit the brakes, as this can cause the vehicle to slip even more. Study your vehicle’s braking system and gears to know the best way to handle your vehicle in an icy situation.
