ATVs are not street legal in Wisconsin for general road use. You cannot ride one down a public highway the way you would a car or motorcycle. Wisconsin Statute 23.33 treats ATVs as off-road vehicles and allows road operation only in a handful of narrow situations: certain crossings, designated ATV routes, seasonally unmaintained roads, and specific government, utility, and agricultural work. Ride outside those exceptions and you can be hit with a forfeiture of up to $250 for a first offense.1Wisconsin State Legislature. Wisconsin Code 23.33(13) – All-Terrain Vehicles and Utility Terrain Vehicles – Penalties
The Narrow Situations Where Road Riding Is Legal
Wisconsin Statute 23.33(4)(d) lists every scenario in which an ATV can lawfully be on a roadway. Each comes with conditions you have to follow exactly.
- Crossing a roadway. You can cross a road to continue on a trail or reach property on the other side. You have to take the most direct route across, stop before entering the road, and yield to all other traffic.
- Seasonally unmaintained roads. If a road is not maintained for regular motor vehicle traffic during certain seasons, you can ride it during those off-maintenance periods, provided the road has not been officially closed to ATVs.
- Bridges, culverts, and railroad rights-of-way. The same direct-route rule applies, and the crossing cannot be on a roadway closed to ATVs.
- Government, utility, and emergency work. Operators of ATVs owned by a municipality, state agency, public utility, or electric cooperative can use roadways when engaged in emergency work or duties tied to the agency’s functions.
- Land surveying. Surveyors can operate on roadways while actively conducting survey work.
Notice what is missing from that list. Recreational riding, commuting, running to the gas station, general transportation. If you are not crossing a road, riding a signed route, or doing one of the specific jobs above, you are riding illegally.2Wisconsin State Legislature.

Designated ATV Routes
The biggest practical exception is the designated ATV route. Counties, towns, villages, and cities can pass ordinances that designate specific roads, or all roads under their jurisdiction, as ATV routes. Once a road is designated and physically marked with ATV route signs, you can ride it legally. No signs, no legal riding.3Wisconsin Department of Transportation.

The 35 MPH Local Option
Separately, a town, village, or city can pass an ordinance authorizing ATV operation on any road within its boundaries with a posted speed limit of 35 mph or less, regardless of which government actually has jurisdiction over that road. This authority is distinct from designating a formal ATV route, and it does not require WisDOT approval. Many smaller Wisconsin communities have used this provision to open local streets.4Wisconsin Department of Transportation. All-Terrain Vehicles and Utility Terrain Vehicles on State Highways
State Highways Are Different
A local government can designate a segment of state highway as an ATV route, but the ordinance is subject to WisDOT review and approval before any signs go up. And an ATV ordinance has to be enacted by a municipality or county before any state-highway operation is permitted at all.4Wisconsin Department of Transportation. All-Terrain Vehicles and Utility Terrain Vehicles on State Highways
The practical rule: just because a road looks like it should be open to ATVs does not mean it is. Look for the posted signs. No signs, off-limits.
Agricultural Use Is Narrower Than It Sounds
Wisconsin law allows ATV operation for agricultural purposes, but the definition is tighter than many riders assume. It covers transporting farm equipment, supplies, or products on a farm or between farms. Riding between your house and a farm does not qualify unless the house sits on the same property as the farm. That trips up people who live a short distance from the land they work.5Wisconsin Department of Natural Resources. 2024 Wisconsin All-Terrain / Utility Terrain Vehicle Laws
What You Risk by Riding Illegally
Most ATV violations in Wisconsin are civil forfeitures rather than criminal offenses. The general penalty for violating any provision of Statute 23.33 is a forfeiture of up to $250. Repeat offenders who tamper with or remove ATV route signs face up to $500. Nonresidents caught operating without a valid trail pass can be fined up to $1,000.1Wisconsin State Legislature. Wisconsin Code 23.33(13) – All-Terrain Vehicles and Utility Terrain Vehicles – Penalties
Operating under the influence is a different level. A first OWI offense on an ATV carries a forfeiture between $150 and $300. Later offenses escalate to fines between $300 and $2,000 and possible jail time ranging from 30 days to one year.1Wisconsin State Legislature. Wisconsin Code 23.33(13) – All-Terrain Vehicles and Utility Terrain Vehicles – Penalties
Check Local Rules Before You Ride
State law sets the floor. Local governments build on top of it. A county, town, village, or city can pass its own ATV ordinance to open or restrict roads beyond what the state allows. Some communities have opened local streets to ATV traffic. Others have passed no ordinance at all, which means no road riding is legal there regardless of speed limit.4Wisconsin Department of Transportation. All-Terrain Vehicles and Utility Terrain Vehicles on State Highways
Before you ride somewhere new, call the town clerk, the county sheriff’s office, or check the municipality’s website for the current ATV ordinance. The Wisconsin DNR also publishes information on public ATV trails and riding areas. A $250 ticket is not worth a guess, and not knowing the road was off-limits is not a defense.
