When you buy a vehicle in Idaho, you will drive away on a temporary plate while your permanent registration is processed. The temporary plate is valid for 30 days, and both dealers and county assessor offices can issue one. Here is exactly how the system works, who qualifies, and what happens if the clock runs out.
How Long Is an Idaho Temporary Plate Valid?
A temporary plate in Idaho is typically valid for 30 days from the date of issue. That window applies whether the plate was issued by a dealership or by your county assessor’s motor vehicle office. There is no automatic extension and no grace period; driving on an expired temporary plate is illegal and may result in fines or other penalties.
The 30-day window is also your title filing deadline. The buyer must file the required documents with a county assessor’s motor vehicle office within 30 days of transfer to avoid a $20 late-filing penalty. In other words, the temporary plate and the title deadline run on the same clock.
Who Issues Idaho Temporary Plates?
Not every situation utilizes the same issuer, as Idaho splits temporary permit responsibilities between retail businesses and local county offices.
Licensed Idaho Dealers
If an Idaho resident purchases a vehicle from an Idaho dealer, that dealer will prepare an application for title for the owner and file it with the Idaho Transportation Department or a county assessor motor vehicle office within 30 days of delivery. As part of that process, the dealer issues a temporary plate at the point of sale at no charge. Dealers are prohibited from billing a separate fee for the permit.
County Assessor’s Motor Vehicle Offices
For private-party purchases and out-of-state transfers, your county assessor’s motor vehicle office issues the temporary plate. County assessors, the Department, licensed Idaho vehicle dealers, or agents of the Department may issue one 30-day temporary registration to out-of-state residents who purchased a vehicle in Idaho and are transporting their newly purchased vehicle to their state of residence. Idaho residents buying from a private seller follow the same process: visit the county office in person with all required documents.
What If I Bought From a Private Seller?
Idaho plates stay with the owner, not the vehicle. When a private seller transfers ownership, they remove their plates. You cannot legally drive the vehicle without either a temporary plate from your county assessor’s office or a completed permanent registration.
The buyer has 30 days from the purchase date to apply for a new title at their local DMV office. If they miss this deadline, they might face penalties. Visit your county assessor’s motor vehicle office as soon as possible after the purchase. Bring the following:
- Original Title: Must be signed and assigned by the seller with all liens fully released.
- Bill of Sale: Complete with the final purchase price, transaction date, and current odometer reading.
- Identification: A valid Idaho driver’s license or state-issued photo ID.
- Proof of Insurance: Documented proof of an active Idaho vehicle liability insurance policy.
- Payment: Funds to cover the required title transfer and standard registration fees.
What Are the Rules for Displaying and Using a Temporary Plate?
To avoid law enforcement citations, you must carefully observe the placement mandates dictated by state code.
Display Requirements
The copy of the application must be displayed in a suitable place on the rear window of a motor vehicle, or if a motorcycle, displayed on the motorcycle. All printed information, including the expiration date, must be clearly visible and unobstructed at all times.
Every license plate shall at all times be securely fastened to the vehicle to prevent the plate from swinging, be at a height not less than 12 inches from the ground, be in a place and position to be clearly visible, and be maintained free from foreign materials and in a condition to be clearly legible. Do not fold, tear, cover, or alter the permit in any way.
What Happens If It Expires?
Do not drive the vehicle on an expired temporary plate. If the delay is on the dealer’s side, title paperwork not submitted within the required 30 days, contact the dealership in writing immediately.
If the vehicle was purchased from an out-of-state dealer or from a private party and a financial institution is recording a lien, they may file the application for title. If no lien is involved and the buyer is responsible for filing, visit your county assessor’s motor vehicle office before the permit expires. Acting before expiration gives you more options than showing up after it has already lapsed.
I Just Moved to Idaho. Do I Need a Temporary Plate?
No. New Idaho residents are not issued a temporary plate; your out-of-state registration and plates remain valid during the transition period.
A $20 late filing penalty can be charged if you do not have a title in your name and you have been living in Idaho for 120 days. The practical advice is to register at your county assessor’s motor vehicle office well before that deadline, most new residents complete registration within the first 90 days of establishing Idaho residency.
