Moving an unregistered vehicle in Idaho requires a temporary permit to avoid hefty fines and potential impoundment. Whether you just purchased a car from a private seller, are transporting a vehicle across state lines, or are waiting for a title transfer, Idaho provides specific short-term solutions.
In 2026, the Idaho Transportation Department (ITD) has shifted toward a “pre-entry” mandate—meaning temporary permits must now be obtained before the vehicle hits the highway, especially for commercial or out-of-state purchases.
Types of Idaho Temporary Permits: 30-Day vs. 120-Hour Trip Permits
Idaho offers two primary types of temporary registration depending on your vehicle’s weight and your residency status.
The 30-Day Temporary Registration: Cost and Eligibility
Following recent legislative updates (HB 21), this is the standard permit for most residents and non-residents.
- Purpose: Moving a newly purchased vehicle to your home or waiting for titling paperwork.
- Cost: $9.00.
- Limit: Restricted to one 30-day permit per vehicle per owner. If you are attempting to sell the vehicle, a second 30-day permit may be granted in emergency situations.
- Ineligible Vehicles: Salvage vehicles (unless rebuilt), vehicles with altered VINs, or commercial loads over 26,000 lbs.
The 120-Hour (5-Day) Trip Permit for Commercial & Out-of-State Vehicles
Mainly used for heavier vehicles or commercial transport.
- Cost: $60.00 for a single vehicle; $120.00 for combinations.
- Context: Often used by non-residents passing through Idaho or carriers not registered under the International Registration Plan (IRP).
- 2026 Rule: This permit must be purchased online or at a Port of Entry prior to entering Idaho.
How to Apply for Your Idaho Permit: Online and In-Person Options
With the launch of Idaho’s New Commercial & Registration System in Spring 2026, the process has become more digital:
- Online: Visit the ITD Port of Entry portal to self-issue 120-hour permits.
- In-Person: Visit any County Assessor’s office for the $9.00 30-day permit.
- Port of Entry: Essential for heavy loads or out-of-state vehicles entering Idaho via major highways.
Requirements for an Idaho Temporary Permit
To secure a permit in 2026, you must provide proof of “lawful operation.” The DMV or a Port of Entry will require:
- Proof of Ownership: A signed-over title or a formal Bill of Sale.
- Identity: A valid state-issued ID or Driver’s License.
- Insurance: Proof of Idaho-compliant liability coverage.
- VIN Inspection: If the vehicle was purchased out-of-state, a $5.00 VIN inspection is required at the time of permit issuance (unless using the 72-hour “Bill of Sale” grace period).
Idaho’s 72-Hour Grace Period: Is a Bill of Sale Enough to Drive?
Many Idaho drivers believe a Bill of Sale acts as an automatic 3-day permit. While some law enforcement agencies allow a 72-hour window to transport a vehicle directly from the point of purchase to a DMV office, this is a discretionary “transit” period. To be 100% legal, you should display the Bill of Sale in the rear window and drive directly to the Assessor’s office.
Frequently Asked Questions
No. Idaho law strictly limits 30-day permits to one per owner. If your titling is delayed, you must apply for a Conditional Registration, which is valid for one year but requires a $21.00 fee and a VIN inspection.
Yes. If you purchase an annual registration within 30 days of issuing the temporary permit, the $9.00 fee can often be credited toward your permanent registration cost, effectively making the permit free for new residents.
If the DMV is closed, keep your Bill of Sale and proof of insurance in the vehicle. Drive only the most direct route to your home or the nearest DMV office on the next business day.
No. Idaho will not issue any temporary or permanent registration for a salvage vehicle until it has been repaired and passes a Salvage Inspection by a certified Idaho law enforcement officer.
Conclusion:
Securing an Idaho temporary registration in 2026 is a $9.00 safeguard against fines. By obtaining your permit before you move the vehicle and ensuring your VIN inspection is completed for out-of-state titles, you can legally operate while the ITD processes your permanent plates. Your next step should be to verify your vehicle’s weight and visit the nearest County Assessor’s office with your original Bill of Sale.
