PORT ROYAL — The Pennsylvania Department of Transportation (PennDOT) placed a radar-controlled speed display board this week on Route 3006 (Mountain Road) in Spruce Hill Township, Juniata County. It is intended to remind drivers to obey the posted speed limit and reduce speeding, a common type of aggressive driving behavior.

The board faces eastbound traffic between Matamoras Road and Run Gap Road on a section of Mountain Road with a speed limit of 40 miles per hour. 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 42 percent of crashes in Juniata County in 2025.
