Idaho IRP and Trip Permits

If you’re running a commercial trucking business across state lines, you’ve probably heard of the International Registration Plan (IRP). IRP is an agreement among states and provinces that simplifies registration by allowing commercial vehicles to register in one jurisdiction and travel across multiple states with a single apportioned plate. Idaho participates fully in IRP - which means if you register your truck in Idaho under IRP, you don’t need to register separately in every state you travel to.

But what if your truck isn’t IRP-registered? That’s where trip permits come in. Idaho offers trip permits as a short-term solution for commercial vehicles that need to travel temporarily without being fully registered under IRP. Let’s look at each option so you know exactly what you need.

What is IRP in Idaho?

The Idaho IRP program is a way for commercial vehicles to register for travel across multiple states under one base plate. It’s specifically for carriers who travel interstate and operate large commercial vehicles.

Who Must Register?

In Idaho, you need IRP registration if your vehicle meets one or more of the following criteria:

Gross weight over 26,000 pounds
Three or more axles
Travel across state lines

Once registered, you pay your registration fees to Idaho, and Idaho distributes those fees to the other states you travel in - making it much easier to stay compliant without worrying about separate plates for every state.

How to Register for IRP in Idaho

If you’re ready to register, the process is straightforward:

Gather your required documents - including proof of ownership (title or lease), proof of insurance, USDOT number, Tax ID number (EIN), and business information.
Complete the Idaho IRP Application.
Submit your application and documents to the Idaho DMV’s Motor Carrier Services unit:
Pay the registration fees. Fees are based on the weight of your vehicle and the miles traveled in each jurisdiction.
Renew annually. Be prepared to file mileage reports every year so Idaho can accurately distribute your fees to other states.

Idaho Trip Permits

If you don’t have IRP plates and need to enter Idaho, a trip permit is your answer. A trip permit is a short-term registration that allows your commercial vehicle to travel legally within Idaho without being IRP-registered. In Idaho, most trip permits last 72 hours.

You’ll need a trip permit if your truck is:

Over 26,000 pounds
Or three or more axles
Or crossing into Idaho from another state without IRP

Fees are calculated by weight and usually start around $28 per trip - though rates can vary, so check the current fees at the Idaho DMV or a permitted service. You can obtain Idaho trip permits online through the Idaho DMV website, at truck stops that offer permitting, or by contacting a third-party trip permit service like us.
