Iowa Snow Plow Tracker and Road Conditions

Q: Where can I see where the plows are in Iowa?

Iowa DOT calls it plow locations, and it runs at https://www.511ia.org/. Iowa DOT describes it this way: "The easiest way to see where we’re plowing in your area is to go to the Iowa 511 site and open the “plow locations” layer. You can also open the “plow cameras” layer to see what our snowfighters are seeing on the roads."

Q: What is Iowa 511?

Iowa 511 is Iowa Department of Transportation's own travel information service. Iowa 511 carries traffic cameras, a phone app called Iowa 511 and a phone line at 511. Iowa DOT describes it this way: "The Iowa 511 website, app, and phone service provide statewide up-to-date traffic information for interstates, U.S. routes, and state highways in Iowa."

The answer

Where the plows are in Iowa

Trucks and plow cameras

Iowa DOT publishes plow positions on Iowa 511 together with photographs taken from cameras mounted on the trucks.

A reader can see a truck move and then look at what its driver is looking at, which is the closest thing any state publishes to standing at the roadside.

What the state calls it: plow locations
Where it lives: Iowa 511
Trucks in the fleet: 850
How often it updates: Iowa DOT states that road condition reports are updated every two hours or as conditions change, and that 511 updates generally are near real time. It publishes no separate refresh interval for plow positions.
By phone: 511

Open plow locations

Iowa DOT describes it in its own words, from About Winter Road Conditions, Iowa Department of Transportation, read September 23, 2026.

The easiest way to see where we’re plowing in your area is to go to the Iowa 511 site and open the “plow locations” layer. You can also open the “plow cameras” layer to see what our snowfighters are seeing on the roads.

The map

What Iowa 511 shows

Iowa 511 carries traffic cameras, a phone app called Iowa 511 and a phone line at 511. Iowa DOT describes it this way: "The Iowa 511 website, app, and phone service provide statewide up-to-date traffic information for interstates, U.S. routes, and state highways in Iowa."

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.

A driver in Iowa can open the 511 map and turn on a plow locations layer to see where the trucks are, a plow cameras layer to see what the drivers see, and an eight step colour legend whose every step Iowa DOT defines in writing.

The words

What Iowa calls each state of a road

Iowa DOT runs 8 steps on Iowa 511, from Seasonal (green) to Towing Not Recommended (light blue shaded county shape). Iowa DOT publishes a definition beside them.

These are Iowa’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.

Iowa DOT’s own labels, in the order Iowa DOT lists them. The second column is the state’s own definition.
What the map says	What Iowa DOT says it means
Seasonal (green)	The roadway is dry or wet, and is generally clear. However, isolated frozen precipitation may exist, including icy bridge decks.
Partially Covered (blue)	Frost, ice, sleet/slush, snow or a mixture of precipitation is causing the roadway to be partially covered. Drivers may experience periods when roadway markings are difficult to see. The roadway surface may become slick, snow packed and rutted. Moderate blowing and drifting snow along with occasional drifts may be encountered.
Partially covered with ice (blue with white dots)	Ice covers a significant portion of the roadway. Although some pavement remains ice-free, traction may be greatly reduced. Drivers should use caution, slow down, and be prepared for sudden slippery spots.
Completely Covered (pink)	The roadway is completely covered with precipitation. Accumulation is to the point that the roadway markings are most likely obscured, making it difficult to differentiate between the roadway and its surroundings. These conditions could make travel difficult or hazardous.
Completely Covered with ice (pink with white dots)	Ice covers the entire roadway. Extremely slippery conditions should be expected, with significantly reduced traction. Travel at reduced speeds and consider delaying trips until conditions improve.
Travel Not Advised (purple)	The roadway has deteriorated to the point that it is very dangerous to travel. Emergency vehicles and snowplows may be called off of the roadway due to the conditions. In the event of an emergency, it may be impossible to get emergency vehicles to the scene.
Impassable or Closed (red with black dots)	A road that is impassable is blocked by snow or disabled vehicles. A road that is closed has travel restricted by barricades, fence, gate, official equipment/vehicles or other physical means. Iowa law prohibits motorists from entering a closed roadway or moving traffic control devices.
Towing Not Recommended (light blue shaded county shape)	It has been determined that weather conditions are, or have deteriorated to the point that it is too dangerous to provide towing or roadside services. Tow truck operators should wait until conditions improve before removing stranded vehicles, for everyone's safety. If your vehicle is stalled or stuck we encourage you find a ride to a safe location.

When a road shuts

Who closes a road in Iowa

Iowa DOT distinguishes a road that is impassable, meaning blocked by snow or disabled vehicles, from a road that is closed, meaning travel is restricted by a physical barrier, and both share one map colour; entering a closed roadway is prohibited by Iowa law.

A road that is impassable is blocked by snow or disabled vehicles. A road that is closed has travel restricted by barricades, fence, gate, official equipment/vehicles or other physical means. Iowa law prohibits motorists from entering a closed roadway or moving traffic control devices.

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 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

Who closes a road in Iowa?

Iowa DOT distinguishes a road that is impassable, meaning blocked by snow or disabled vehicles, from a road that is closed, meaning travel is restricted by a physical barrier, and both share one map colour; entering a closed roadway is prohibited by Iowa law. Iowa DOT puts it this way: "A road that is impassable is blocked by snow or disabled vehicles. A road that is closed has travel restricted by barricades, fence, gate, official equipment/vehicles or other physical means. Iowa law prohibits motorists from entering a closed roadway or moving traffic control devices."

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

Departments replace these services between seasons and a layer that ran last winter may not run this one, so Iowa DOT’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.
