Clearfield, PA – The Pennsylvania Department of Transportation (PennDOT) placed a radar-controlled speed display board this week on Route 322 in Rush Township, Centre County. It is intended to remind drivers of commercial vehicles to obey the posted truck speed limit on a section of roadway with a significant downward grade.
The board faces eastbound traffic on Route 322 at the top of Port Matilda Mountain, between Hanah Furnace Road and Sandy Ridge Trail, in an area zoned 30 miles per hour for commercial vehicles. The board utilizes radar to determine the speeds of oncoming traffic and posts them to the lighted section of the sign.
The board will remain in this location for four to six weeks.
Speeding and other aggressive driving behaviors are among the leading causes of Pennsylvania crashes and fatalities. Other aggressive driving behaviors include running stop signs or red lights, passing illegally, and tailgating.
PennDOT listed aggressive driving behaviors as a factor in 61 percent of crashes in Centre County in 2025.
