Idaho License Plate Law: Front Plate Required
Yes. Idaho Code §49-428 requires two license plates (front and rear) on all registered motor vehicles — cars, trucks, SUVs, vans, trailers, and commercial vehicles.
Exceptions
- Motorcycles: Rear plate only (Idaho Code §49-428(2))
- Trailers ≤1,000 lbs GVW: Rear only
- Dealer/Transporter plates: Specific rules
- Classic/Old Timer plates (vehicles ≥30 years): May qualify for single rear plate — check ITD
Penalties
- Infraction: $67.50 fine (2024 schedule)
- Traffic Stop Basis: Missing front plate = valid reason for stop
- Inspection Failure: Annual/safety inspection requires both plates
Mounting Requirements
- Securely fastened, horizontal, visible, unobstructed
- Front: 12-48 inches above ground
- No covers/tints that reduce reflectivity/legibility
- Plate frame allowed if doesn't obscure state name, tags, numbers
Context
30 states require front plates. Idaho's neighbors: WA, OR, MT, WY, UT, NV — only NV and UT require front. Border-state commuters often non-compliant. ITD emphasizes compliance for tolling (future), automated enforcement, witness identification.
Bottom Line: Put the front plate on. $67.50 isn't worth the hassle, and it's the law.
