Utah puts its plows on the map

Utah Snow Plow Tracker and Road Conditions

Utah puts both things on one map: UDOT Traffic carries a Snow Plows layer where selecting a truck draws the path it has just plowed with a time on every breadcrumb, alongside a winter road conditions layer coloured Unknown, Low, Moderate or High.

The answer

Where the plows are in Utah

Trucks on the map

UDOT publishes where its plows are and when a plow last came past on UDOT Traffic.

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.

The map

What UDOT Traffic shows

UDOT Traffic carries 1200 traffic cameras, a phone app called UDOT Traffic App and a phone line at 511. UDOT describes it this way: "UDOT provides information about statewide road conditions on the UDOT Traffic website and mobile app which supplies access to over 1,200 cameras, 200 message boards, and in-road and roadside sensors."

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 Utah calls each state of a road

UDOT runs 4 steps on UDOT Traffic, from Unknown to High. UDOT publishes a definition beside them.

These are Utah’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.

UDOT’s own labels, in the order UDOT lists them. The second column is the state’s own definition.

When a road shuts

Who closes a road in Utah

UDOT designates Class I and Class II Traction Segments by administrative rule, and UDOT, the Utah Highway Patrol or a designated local law enforcement agency decides when conditions warrant keeping vehicles without traction devices off those segments.

When road surface conditions warrant, as determined by UDOT, UHP or designated local law enforcement agency, no vehicle will be allowed or permitted the use of the highway unless:

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, and the state also takes reports of conditions from the public.

A red and white striped gate padlocked shut across a two lane forest highway with a ROAD CLOSED sign at its centre, photographed at road level along the wet double yellow line
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

Utah 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

Utah read September 23, 2026 from About UDOT Traffic, Utah Department of Transportation, linked above. Departments replace these services between seasons and a layer that ran last winter may not run this one, so UDOT’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.
