Pennsylvania Department of Transportation (PennDOT) Winter Driving Tips
Some areas in the Northeast and Midwest are seeing record low temperatures and historic levels of snow. One major road hazard is black ice, which dramatically reduces traction and is virtually invisible.
Black ice forms when the ground temperature causes precipitation to freeze upon impact. The highest-risk areas include driveways, roadways, bridges, overpasses and ramps.

 
The Pennsylvania Department of Transportation (PennDOT) offers these tips for driving in ice this season:

Before getting on the roads when it is cold and wet, drivers should check the area’s weather conditions in order to be informed.

Stay calm and let the vehicle pass over the black ice.

Lift your foot off the accelerator.

Do not hit the brakes, yet keep your steering wheel steady.

Do not overcorrect your steering if you feel your car sliding.

Be cautious. Slow down and increase your following distance between your vehicle and the one in front of you.

Other tips for safe driving this winter season:

Carry a winter emergency travel kit.

Listen to weather and travel advisories, but if you don’t have to travel in bad weather, don’t.

Keep your gas tank at least half full.

Slow down and increase following distance.

Avoid sudden stops and starts.

Beware of roads that may look wet, but are actually frozen, often referred to as “black ice.”

Use extra caution on bridges and ramps, where ice can often form without warning.

Carry a cell phone.

Do not use cruise control while driving on snow-covered roads.

State law requires you to turn on your headlights when your wipers are on.

Use your low beams in particularly bad weather, especially in cases of heavy or blowing snow.

Remove ice and snow from windows, mirrors and all vehicle lights […]
