HARRISBURG – Ahead of heavy snow expected across Pennsylvania starting Saturday night, the Pennsylvania Department of Transportation (PennDOT) and the Pennsylvania Turnpike Commission (PA Turnpike) are planning to implement vehicle restrictions across Pennsylvania’s Interstate network.

The agencies are also advising drivers to watch weather forecasts, avoid unnecessary travel if possible and to exercise caution when driving.

Heavy snow is expected across the Commonwealth starting Saturday night, with snowfall rates of 1″ to 2″ per hour by the afternoon on Sunday. Temperatures will be very cold and are expected to remain below freezing across the state throughout next week.

Restrictions are planned for certain vehicles during the storm, and will be communicated via variable message boards, the 511PA traveler information website and smartphone apps. Drivers can also sign up for personalized alerts on the website. Restrictions will be lifted as quickly as possible when conditions permit. Restrictions can be changed based on conditions on the roadways, and reports from first responders, law enforcement and PennDOT personnel.

The following vehicle restrictions are planned to go into effect at 12:01 a.m. on Sunday, Jan. 25 in accordance with Tier 4 of the commonwealth’s weather event vehicle restriction plan.

All Pennsylvania interstates including:

– PA Turnpike I-76

– PA Turnpike I-70

– All PA Turnpike extensions.

– U.S. 15 from I-180 to the New York border.

– U.S. 22 from Route 66 to I-99.

– U.S. 22 from I-78 to the New Jersey border.

– U.S. 219 from U.S. 30 to U.S. 22.

– U.S. 220 from I-80 to I-180.

– U.S. 322 from Interstate 99 to I-81.

– Route 28 from I-279 to U.S. 422.

– The entire length of Route 33.

On roadways with Tier 4 restrictions in place, no commercial vehicles are permitted. Additionally, all school buses, commercial buses, motor coaches, motorcycles, RVs/motorhomes and passenger vehicles (cars, SUVs, pickup trucks, etc.) towing trailers are not permitted on affected roadways while restrictions are in place.

Speed limits will be restricted to 45 mph on these roadways for all vehicles while the vehicle restrictions are in place, and commercial vehicles not affected by the restrictions must move to the right lane. Additional speed restrictions on other interstates could be added depending on changing conditions.

While avoiding or delaying unnecessary travel during winter storms is the safest choice, PennDOT offers this advice if drivers must travel and encounter snow squalls or blowing or drifting snow:

– Slow down gradually and drive at a speed that suits conditions.

– Turn on your headlights. If caught in a snow squall, turn on your hazard lights.

– Stay in your lane and increase your following distance.

– Stay alert, keep looking as far ahead as possible and be patient.

– Do not drive distracted; your full attention is required.

– Use your defroster and wipers.

– Keep windows and mirrors free of snow and ice.

– During whiteouts, come to a complete stop only when you can safely pull off the roadway.

– Do not stop in the flow of traffic since this could cause a chain-reaction collision.

– Do not pass a vehicle moving slowly or speed up to get away from a vehicle that is following too closely.

– Always buckle up and never drive impaired.

– Have an emergency kit handy.

Last winter in Pennsylvania, preliminary data shows that there were 8,329 crashes, 29 fatalities and 2,959 injuries on snowy, slushy or ice-covered roadways. Eleven of the people who died weren’t wearing a seat belt, and 17 of the fatalities were in crashes where a driver was going too fast for conditions and drove out of their lane.
