​Where's My Plow?

The public can view all of PennDOT's snow plows on the road during a winter storm at

In 2014, PennDOT began a pilot equipping 119 plow trucks with the Automated Vehicle Location (AVL) system, which uses in-truck technology to log and share data in real-time for that truck. That pilot expanded to more than 700 plow trucks last winter that were publicly viewable on

This winter, all of the more than 2,200 PennDOT-owned and rented plow trucks will be equipped with AVL technology — meaning the public can view the trucks on interstates and expressways this winter at

The AVL unit in each truck sends a cellular signal through the system showing where a truck is located and whether or how much material is being spread from the truck.


PennDOT uses AVL to:

  • Monitor vehicle movement and plow-route coverage;
  • Monitor the system during winter storms or emergencies and, if needed, see the closest truck to an area that needs additional service and direct trucks to that location;
  • Review data on effectiveness in returning traffic to pre-storm conditions;
  • Review usage of materials such as salt and anti-skid through the various stages of a weather event; and
  • Interface with other department technology to combine real-time weather and road conditions with corresponding material-usage rates.

The AVL system pilot is part of Governor Wolf's GO-TIME initiative that leverages interagency coordination and collaboration to maximize efficiency, modernize state government operations, and provide the highest-quality services. 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.
