Restrictions will remain in place as long as conditions warrant. As conditions develop, speed restrictions will be considered on these routes. If the forecast changes, PennDOT will quickly review and possibly adjust or lift the restrictions.

If traveling during severe winter weather, motorists should make sure their gas tank is full and they pack an emergency kit, which should include non-perishable food, water, blanket, small shovel and warm clothes. Remember also any special needs, such as baby food, pet supplies or medications.

When queues form and roadways are expected to be closed for long periods because of crashes and other traffic disruptions, PennDOT and the Pennsylvania Emergency Management Agency can activate the 511PAConnect system to establish contact via cellphone to trapped motorists.

Motorists are reminded that roadways will not be free of snow while precipitation is falling. With freezing temperatures, roads that look wet may be icy, and extra caution is needed when approaching bridges and highway ramps where ice can form without warning. Motorists should leave plenty of space – six car lengths --- when following a truck that is plowing or spreading winter materials. Also, reduced speeds are a must when traveling during snow events.

While driving in severe weather, motorists should follow these protocols:

-        always travel at a safe speed for conditions, no matter what the posted limit is;

-        allow plenty of space when driving near plow trucks; and

-        never pass a truck that is actively plowing or spreading salt

While PennDOT recommends not traveling during winter storms, motorists are encouraged to “Know Before You Go” by checking conditions on more than 40,000 roadway miles by visiting www.511PA.com. 511PA, which is free and available 24 hours a day, provides traffic delay warnings, weather forecasts, traffic speed information and access to more than 850 traffic cameras. Users can also see plow truck statuses and travel alerts along a specific route using the “Check My Route” tool.

511PA is also available through a smartphone application for iPhone and Android devices, by
