Idaho Truck Permits for trip, fuel, oversize & overweight

A truck without Idaho registration or IFTA runs on one combined trip permit: 120 hours in place of registration, IFTA or a temporary weight increase, issued by ITD Motor Carrier Services. Idaho allows three per calendar year, and a non-IFTA diesel truck over 26,000 lbs pays an extra charge on the same permit. Oversize and overweight loads need a permit from the Idaho Transportation Department. Tell us the truck, load and route, and we file every Idaho permit the trip needs.

Idaho and Wyoming

How Idaho permits differ from Wyoming's

Next-door states with different trip permits, weight limits and weather rules.

  1. One trip permit or two

    Idaho folds registration and fuel into one 120-hour trip permit, three a year. Wyoming sells a 96-hour registration trip permit and a separate 96-hour fuel permit.

  2. Gross weight on the interstate

    Idaho holds the interstate to 80,000 lbs and allows up to 105,500 lbs off it. Wyoming allows up to 117,000 lbs on the interstate by bridge table, no permit needed.

  3. Heavy combinations

    Idaho runs LCVs up to 129,000 lbs on designated routes. Wyoming allows doubles and triples within 81 ft of trailers.

  4. Wind

    In Idaho, wind over 40 mph makes an oversize permit invalid en route. Wyoming closes roads to light, high-profile vehicles by wind class, 1 to 4.

FAQ

Idaho permit questions

What does Idaho's 120-hour trip permit stand in for?

Idaho registration, IFTA or a temporary weight increase. One permit covers whichever the truck is missing for 120 hours, issued by ITD Motor Carrier Services.

Is there a cap on Idaho trip permits per year?

Yes, three per calendar year. We check how many have been used before filing the next one.

Does a non-IFTA diesel truck pay more for the Idaho trip permit?

Yes, over 26,000 lbs. The extra charge goes on the same trip permit, so no separate fuel permit is needed.

Do oversize loads stop at Idaho ports of entry?

At every port on the route: Bonners Ferry, Huetter, Lewiston, East Boise, Horseshoe Bend, Marsing, Declo, Hollister, Inkom and Sage Junction. We have the ITD permit filed before the first one.

Can one request cover the Idaho trip permit and the ITD oversize permit?

Yes. Send the truck, load and route; our permit desk files the 120-hour trip permit, the ITD oversize permit and the permits for the states on either side, around the clock.
