I-80 Speed Limit Reduced through Clarion and Jefferson Counties

Indiana, PA – Due to the severity of the winter storm PennDOT is temporarily reducing the speed limit to 45 miles per hour (mph) on Interstate 80 in Clarion and Jefferson counties.

The speed limit restriction is in place from the Ohio state line to Exit #97:  US 219 – DuBois/Brockway.  Speed limits are restricted to 45 mph for all vehicles, and commercial vehicles must move to the right lane.

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

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. Motorists can also sign up for personalized alerts on the website. Restrictions will be lifted as quickly as possible when conditions are safe. Restrictions can be changed based on conditions on the roadways, and reports from first responders, law enforcement and PennDOT personnel.

When winter weather occurs, drivers should be extra cautious around operating snow-removal equipment. When encountering a plow truck, drivers should:

  • Stay at least six car lengths behind an operating plow truck and remember that the main plow is wider than the truck.
  • Be alert since plow trucks generally travel much more slowly than other traffic.
  • When a plow truck is traveling toward you, move as far away from the center of the road as is safely possible, and remember that snow can obscure the actual snow plow width.
  • Never try to pass or get between several trucks plowing side by side in a "plow train." The weight of the snow thrown from the plow can quickly cause smaller vehicles to lose control, creating a hazard for nearby vehicles.
  • Never travel next to a plow truck since there are blind spots where the operator can't see, and they can occasionally be moved sideways when hitting drifts or heavy snowpack.
  • Keep your lights on to help the operator better see your vehicle. Also remember that under Pennsylvania state law, vehicle lights must be on every time a vehicle's wipers are on due to inclement weather.
