Ahead of freezing precipitation forecast across Pennsylvania on Tuesday, the Pennsylvania Department of Transportation (PennDOT) is planning to implement vehicle restrictions across Pennsylvania’s Interstate network and on some other high-traffic roadways. Drivers are advised to watch weather forecasts, avoid unnecessary travel if possible and to exercise caution when driving.
In areas without salt residue on the roadway from previous storms, PennDOT may pretreat with salt brine, essentially a mix of water and salt, from the backs of anti-icing trucks before frozen precipitation starts to fall. Salt brine isn’t appropriate for every storm, but when it’s used it helps prevent precipitation from bonding to the road and gives the department a jump start on removing ice and snow.
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. 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 3:00 AM on Tuesday, March 3, in accordance with Tier 1 of the commonwealth’s weather event vehicle restriction plan.
- I-80 from I-79 to Exit 173.
- I-99 entire length.

- I-180 from I-80 to U.S. 220.

Speed limits will be restricted to 45 mph on these roadways for all vehicles when conditions warrant, 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.
