How many times have you driven down a snow-covered road and wondered where the snow plow could be?

Pennsylvanians can now go online or check an app to find the location of PennDOT plows.

As part of an expanded technology pilot program, the public can now view hundreds of plow trucks on interstates and expressways this winter at www.511PA.com,.

Governor Tom Wolf announced on Monday that the Automated Vehicle Location (AVL) system provides information on vehicle movement and usage of winter materials.

The public can view the location of more than 500 PennDOT plow trucks and more than 200 contracted rental trucks this winter through the 511PA website.

PennDOT Secretary Leslie S. Richards explained that while on-duty trucks will be shown in near real-time, the pilot does not show all of the department’s services on interstates or expressways, or statewide.

“During winter weather, interstates and expressways are our top priority,” Richards said. “That means that we often move trucks from lower-traffic roads onto interstates, and those trucks won’t be shown on 511.

Additionally, due to differing staff schedules, storms or equipment usage, the location of all of the trucks will not be visible at all times. Users will not see all of PennDOT's more than 2,000 trucks across the state.

Statewide, PennDOT has more than 2,200 total department-force trucks and also rents approximately 270 trucks and their operators to maintain the more than 40,000 miles of roadway for which PennDOT is responsible.

The pilot, as one of seven GO-TIME projects identified by PennDOT in 2016-2017, is expected to realize a cost savings of $1.4 million over the next four to six years based on a combination of reduced salt usage and better use of department equipment.
