Wisconsin Trip and Fuel (IRP / IFTA) Permits

Wisconsin’s 72-hour trip permits authorize one round-trip into and out of Wisconsin. For vehicles registered in Iowa, Michigan, and Minnesota, a trip permit is needed beyond the reciprocity zones.

Only applicants wishing to move vehicles into Wisconsin that are not registered in Wisconsin nor enrolled into either IRP or IFTA are eligible for 72-hour trip permits. Applicants who want to move unregistered vehicles within or out of Wisconsin are not eligible. The 72-hour trip permit may not be purchased to authorize movement of unregistered vehicles for trips beginning in Wisconsin.

Exempt "for hire" carriers operating intrastate must have Wisconsin authority and insurance on file prior to obtaining a trip permit.

US Department of Transportation exempt "for hire" carriers must have Wisconsin authority and insurance on file prior to obtaining a trip permit.

Most applicants buy both registration and fuel, but the temporary registration and the in-lieu-of fuel tax portions may be purchased separately. The fee for each part is $15, for a total of $30 if both are purchased.

Payment may be made with a valid credit or debit card (Visa, MasterCard, Discover or American Express) or ACH (Automated Clearing House) payment from your checking or savings account. Your credit or debit card will be charged a convenience fee for this service. There is no convenience fee charged for ACH payment.

This permit is not accepted in electronic format and must be presented in paper form. Please print the final permit.

Wisconsin Overweight / Oversize Fines

Whenever any owner or operator is convicted of violating weight/overweight laws or any local ordinance in conformity with weight/overweight laws or any ordinance enacted under s. 349.15 (3), the clerk of the court in which the conviction occurred, or the judge or municipal judge, if the court has no clerk, shall, within 48 hours after the conviction, forward a record of conviction to the department. Forfeiture of bail or appearance money or payment of a fine is a conviction within the meaning of this section.

For the first conviction in the year the fine will be between fifty ($50) and two hundred ($200) dollars. For the first conviction in the year the fine will be the above costs plus the following:

WEIGHT                 FINE

1 – 2,000 lb.           $.01 cents per pound overweight

2,001 – 3,000 lb.   $.03 cents per pound overweight

3,001 – 4,000 lb.   $.05 cents per pound overweight

4,001 – 5,000 lb.   $.08 cents per pound overweight

Wisconsin Frost Laws

Effective as of Saturday, March  2020, Wisconsin's frozen road law expanded to include regions designated by the Wisconsin Department of Transportation (WisDOT) as Zone 3 and 4. The expansion  covers the state except for Zone 5 in southeast Wisconsin.


The frozen road determination for Zone 5 will be made once conditions warrant.  


The frozen road law allows heavier loads for trucks carrying logs cut crosswise (not including woodchips), and salt and sand for winter maintenance while cold weather allows.


WisDOT and county highway personnel monitor temperature forecasts, along with frost tubes -- liquid-filled devices under pavement -- to help determine when roads are adequately frozen to accommodate heavier loads.


The declaration is issued once the ground under highway pavement is frozen to a depth of at least 18 inches, allowing the maximum gross weight for trucks hauling logs or salt and sand for maintaining roads in winter to go up to 98,000 pounds on vehicles with a minimum of five axles (from the normal 80,000 pounds). Special permits for hauling the increased weights are not required in Zone 1, but vehicles must be legally licensed at 80,000 pounds to handle the increased weights. The higher weight limits do not apply to county or local roads unless authorized by the local agency having maintenance authority. Also, higher weights may not be transported on any highways or bridges specifically posted for lower weight limits.

Wisconsin Road Conditions

Each year in Wisconsin, both highway workers and motorists are killed and injured in crashes that happen in highway construction zones.

To protect themselves and highway workers, drivers need to slow down whenever they see flashing lights, or move over, if possible, to leave the lane beside the work zone open. In some construction areas, lowered speed limits are posted and must be obeyed at all times.

Remember, when you enter a work zone, be patient.

  • Orange Cones -- put down the phones!
  • Don’t fool around. Eliminate distractions like eating, drinking, talking on the phone, or fiddling with electronic devices.
  • Expect the unexpected. Speed limits may be reduced, traffic lanes may be changed, and people and vehicles may be working on or near the road.
  • Slow down. A car traveling 60 mph travels 88 feet per second, and the faster you go the longer it takes to stop.
  • Give yourself room. Rear-end collisions are the most common work zone crashes, so don’t tailgate.
  • Allow about three seconds of braking distance. Look for signs. Orange, diamond-shaped signs usually give you ample warning of lane closings, construction areas, and flaggers and other workers ahead.
  • Be patient. If you don’t see workers, that doesn’t mean they’re not there. Observe the signs until you see one that says you’ve left the work zone.
  • Plan ahead. Leave early or map out an alternate route. Find the latest road conditions and work zone news at 511 Wisconsin.
  • Follow the law. Slow down and move over, if possible, when you see flashing lights.
