Pennsylvania puts its plows on the map

Pennsylvania Snow Plow Tracker and Road Conditions

Pennsylvania is one of the states that puts the trucks themselves on the map: every PennDOT plow carries automatic vehicle location, so 511PA shows plows working during a storm and the tracks they left over the last several hours, alongside a road condition colour from normal to impassable.

The answer

Where the plows are in Pennsylvania

Trucks on the map

PennDOT publishes where its plows are and when a plow last came past on 511PA.

A reader can see which roads have a truck on them right now. Whether one has already been past is a separate question the layer may or may not answer.

Shows a last pass
Yes. The layer records when a truck was last down a road, not only where one is now.
Trucks in the fleet
2,200
How often it updates
PennDOT says each truck's location and material spreading are logged and shared in real time, and the map's plow layer also draws where trucks have been, from now back six hours on a route and from six to twelve hours on any route.

What 511PA shows

511PA carries traffic cameras, a phone app called 511PA app and a phone line at 511. PennDOT describes it this way: "Provides up to the minute traffic and transit information for Pennsylvania. View the real time traffic map with travel times, traffic accident details, traffic cameras and other road conditions."

Conditions on any state map are reported rather than measured. A plow operator or a trooper enters what they saw, and the map carries it until somebody enters something else, so a colour is a description of the road a while ago on the stretch the person was looking at.

The words

What Pennsylvania calls each state of a road

PennDOT runs 6 steps on 511PA, from Normal Conditions to Impassable. PennDOT prints the labels without defining them.

These are Pennsylvania’s words and they stop at the state line. There is no national scale: the 33 states that publish a legend use 166 different labels between them, and only 17 publish what their own labels mean. A phrase that means one thing here means something else, or nothing, one state over.

PennDOT’s own labels, in the order PennDOT lists them. The state prints these labels without defining them.
What the map says
Normal Conditions
Wet with Freezing Conditions
Snow and / or Slush Covered
Snow Packed / Significant Snow Cover
Icy
Impassable

When a road shuts

Who closes a road in Pennsylvania

Pennsylvania's winter storm tool is a tiered restriction on commercial vehicles rather than a blanket closure, and three agencies decide it together and revisit it every hour.

PennDOT, the Pennsylvania State Police, and the Pennsylvania Emergency Management Agency assess each winter weather forecast to determine if CMV restrictions are warranted. Then, they review the restrictions hourly once they have been initiated to determine if the conditions warrant the restriction or can be lifted.

A closure is a different thing from a bad condition, and it is the one entry on the map that carries the force of law behind it. Driving past a closure device is an offence in most states and a rescue bill in several. The map is where the closure is published.

A seasonal gate shut across a state highway, with no snow on the ground yet. Closures like this one go on by the calendar rather than by the storm, and a driver who checks the map in November finds the road already gone. That is the quietest and most useful thing these maps do, and it happens weeks before anybody looks for a plow. “The gates are closed (49097728041)”, Oregon Department of Transportation, CC BY 2.0

Pennsylvania snow plow tracker questions

A plow truck seen from behind in heavy snowfall casting a wide plume of snow off the left shoulder of an interstate, with one dark treated lane running away to the right
The same event from behind: the truck throwing its wing load onto the shoulder, and beside it the dark strip of lane it has already been down. That contrast between the wet black lane and the white one is the physical thing a road map is reporting when it changes a segment from snow covered to wet, and it is why the colour on the map can be right and the road can still be slick. “Snowplow on Interstate 5 in Everett, Washington”, SounderBruce, CC BY-SA 4.0

Pennsylvania read September 23, 2026 from 511PA, Pennsylvania Department of Transportation, linked above. Departments replace these services between seasons and a layer that ran last winter may not run this one, so PennDOT’s own page is the one that governs. Conditions shown on it are reported by people and lag the road. Every state is on the snow plow tracker hub.
