PennDOT Reduces Speed Limit on Interstate 99 in Response to Winter Storm Izzy

Clearfield, PA – Due to the severity of the winter storm, PennDOT is temporarily reducing the speed limit on Interstate 99 in Centre County to 45 mph. 

Under Tier 2 restrictions, the following vehicles are not permitted on affected roadways:

Tractors without trailers

Tractors towing unloaded or lightly loaded enclosed trailers, open trailers or tank trailers

Tractors towing loaded tandem trailers unless there are chains or another approved Alternate Traction Device on board

Enclosed cargo delivery trucks that meet the definition of a CMV

Passenger vehicles (cars, SUV’s, pickup trucks, etc.) towing trailers

Recreational vehicles/motorhomes

School buses, commercial buses and motor coaches and

motorcycles.

On roadways with speed restrictions, commercial vehicles not affected by restrictions on these or other roadways must move to the right lane.

The purpose of the restriction is to help ensure the interstates remain open during the most challenging conditions of the winter storm. When conditions improve, PennDOT will remove the travel restrictions. 

Restrictions will be communicated via variable message boards, the 511PA traveler information website at www.511PA.com and smartphone apps. Motorists can also sign up for alerts on the website.

Although PennDOT crews are treating roadways, the department’s primary goal is to keep roads passable, not completely free of ice and snow. PennDOT will continue to treat roadways throughout the storm until precipitation stops and roads are clear.

While PennDOT recommends not traveling during winter storms, motorists can check conditions on more than 40,000 roadway miles, including color-coded winter conditions on 2,900 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 1,000 traffic cameras. 

511PA is also available through a smartphone application for iPhone and Android devices, by calling 5-1-1, or by following

regional Twitter alerts.
