PennDOT Line Painting Operations Starting in Northwest Region

The Pennsylvania Department of Transportation’s (PennDOT) northwest region is reminding motorists that line painting operations will get underway this month, weather permitting.

The six-county region, which includes Crawford, Erie, Forest, Mercer, Venango, and Warren counties, owns two paint trucks to paint more than 4,700 miles of lines each year. The equipment is scheduled to complete line-painting operations throughout the region in the coming months, starting with the interstates.

Motorists who encounter a line-painting operation should follow these guidelines:

  • Stay back at least 500 feet from the equipment.
  • Don’t drive on wet paint lines.
  • Don’t pass the trucks in a paint train.
  • Be patient as the paint truck will pull over periodically to let traffic pass.

Weather conditions often effect how quickly line paint will dry. Under ideal temperatures and humidity, the average time for the paint to be no track is 90 to 120 seconds. During the early spring and late fall, it can take several more minutes for the paint to completely dry.

Drivers are responsible to operate their vehicles within the roadway lines and follow all warning and advisory signage. Additional information on the statewide line painting effort is available on PennDOT’s website,
