On February 13, 2026, the Pennsylvania Department of Transportation announced that investments in Variable Speed Limit (VSL) signage on Interstates 80 and 81 have led to a reduction in crashes and fatalities during winter weather. The announcement was made during a visit to PennDOT’s District 2 Regional Traffic Management Center in Clearfield.
The implementation of VSL signs is part of broader efforts by state agencies to improve road safety during hazardous winter conditions. Data shows that these signs have resulted in an average of seven percent fewer winter crashes and a thirty-four percent decrease in serious injuries and fatalities at affected locations. The initiative is supported by the Pennsylvania Turnpike Commission, Pennsylvania Emergency Management Agency, Pennsylvania State Police, and the National Weather Service.
“Safe driving is important year-round, but it’s even more essential in the winter when weather conditions can change quickly (…) If you receive a snow squall warning while driving on an interstate, the best thing to do is take the next exit and find a safe place to park. If that’s not possible, stay in your lane and slow down gradually, increasing your following distance. Turn on your headlights and hazard lights so other vehicles can see you. And buckle up! Your seat belt could save your life if you are in a crash,” according to PennDOT Secretary Mike Carroll.
The agencies also highlighted resources available for drivers, including a free snow squall driving simulation developed by Hofstra University Professor Dr. Jase Bernhardt in partnership with the National Weather Service. “This immersive VR simulation places drivers in a realistic snow squall scenario complete with many of the visual and audible cues a Pennsylvania motorist would encounter (…) By experiencing these conditions firsthand, drivers gain a deeper understanding of snow squall severity and the recommended life-saving actions to take when a Snow Squall Warning is issued,” according to NWS Warning Coordination Meteorologist Jonathan Guseman.
Variable speed limit signs are installed at multiple locations along I-80, I-81, and I-70/76 based on crash data and frequency of wintry conditions requiring safer driving speeds. When activated due to poor visibility or hazardous weather, these electronic signs display reduced speed limits accompanied by flashing yellow lights.
“Drivers can be cited for driving too fast for conditions, even if they are below the posted speed limit, if weather or road conditions make their speed unsafe for the existing hazards (…) If you are involved in a crash on a slippery road, do not stand outside your vehicle on or near the roadway. In most situations, you will be safer inside your vehicle with your seatbelt fastened and your hazard lights activated,” according to PSP Acting Commissioner Lieutenant Colonel George L. Bivens.
