PennDOT Preparing For Wintry Weather

AAA safe driving tips for slick or icy roadways:

• Slow down: Adjust your speed to the road conditions and leave yourself ample room to stop. Allow at least three times more space than usual between you and the car in front of you.
• Do not tailgate: normal following distances of three to four seconds on dry pavement should be extended to a minimum of eight to ten seconds when driving on slippery surfaces. The extra time will provide additional braking room should a sudden stop become necessary.
• Never use cruise control on slippery roads: patches of ice can cause unexpected wheel spin and use of cruise control can slow driver response.
• Avoid unnecessarily changing lanes: this increases the chances of hitting a patch of ice between lanes that could cause loss of vehicle control.
• Use extreme caution on bridges and overpasses: black ice typically forms first in shaded areas of the roadway and on bridges and overpasses that freeze first and melt last. Although the road leading up to a bridge may be fine, the bridge itself could be a sheet of ice.
• Move Over: move over one lane for law enforcement and emergency roadside personnel assisting motorists. It is the law. If you are unable to move over, slow down.
• Think 'Ahead' - Keep a close eye on traffic ahead and slow down immediately at the sight of brake lights, fishtailing cars, sideways skids or emergency flashers ahead.
• Carry your AAA Membership Card - program your phone with the AAA HELP number and your AAA membership number to expedite the rescue process in the event of a breakdown (1-800-AAA-HELP)
