Whether you need a front license plate in Idaho depends on one thing: whether your vehicle came from the factory with a front license plate mounting bracket. If it did, the front plate is required. If it didn’t, you’re exempt. A 2025 amendment to Idaho Code § 49-428 tied the front plate requirement directly to the presence of a manufacturer-installed bracket, which took effect July 1, 2025.1Idaho State Legislature.

How the Factory Bracket Rule Works
Before Senate Bill 1180 took effect, Idaho required every standard passenger vehicle to display plates on both the front and the rear. The new rule keeps the two-plate requirement only for vehicles that shipped from the manufacturer with a front bracket installed.1Idaho State Legislature. Idaho Code 49-428 – Display of Plate and Stickers Many sports cars and certain trucks never came with one, and their owners no longer have to mount a front plate.
Two details are worth pinning down. Aftermarket brackets do not count. The statute specifically references a bracket installed by the manufacturer, so a bracket added by a dealer or a previous owner does not create a requirement. On the other side, you can’t remove a factory bracket to claim the exemption. What matters is whether the bracket was there when the vehicle was manufactured.
You’ll Still Receive Two Plates
Even if your vehicle is exempt from displaying a front plate, the Idaho Transportation Department continues to issue two plates with every standard registration. Hold onto the unused one. You’ll need it if you sell the vehicle to someone in a state that requires two plates, or if you move the registration to a vehicle that does have a factory bracket.
Vehicles That Only Get One Plate to Begin With
Some vehicles never enter the front-plate question because Idaho issues them a single plate:
- Motorcycles, displayed on the rear
- Trailers and semitrailers, displayed on the rear
- Truck-tractors, displayed on the rear
- ATVs, UTVs, and motorbikes, which receive a restricted vehicle plate
Tractors are the odd one out. A tractor’s single plate mounts on the front rather than the rear.1Idaho State Legislature. Idaho Code 49-428 – Display of Plate and Stickers
Collector and Specialty Plates
If your vehicle carries year of manufacture, old timer, classic car, street rod, or custom vehicle plates, you can mount a single plate on the rear regardless of whether the vehicle has a front bracket.1Idaho State Legislature.

What Happens if You Skip a Required Front Plate
Failing to display a required plate is a non-moving traffic infraction. The total fine for a violation of § 49-428 is $67, made up of a $10.50 fixed penalty and $56.50 in court costs, surcharges, and fees, set statewide as of July 1, 2025.2Idaho Supreme Court.

If you’re unsure whether your vehicle has a factory bracket, check behind the front bumper cover before deciding to leave the front plate off.
