Commercial Vehicles and the Wyoming Lemon Law
How Wyoming's lemon law treats commercial and work vehicles — the under-10,000-lb-unladen weight limit, the not-for-resale requirement, and the Magnuson-Moss backup.
Commercial and work vehicles get partial lemon-law coverage in Wyoming — important in a state built on energy and ranching. The gatekeeper is unladen weight, and the vehicle must be purchased other than for resale.
The weight limit (unladen, not GVWR)
Wyoming’s lemon law covers a self-propelled vehicle under 10,000 pounds unladen weight, sold or registered in Wyoming, purchased other than for resale (§ 40-17-101). Two points follow:
- Unladen (curb) weight is the measure — not GVWR. A half-ton or many light trucks fall under 10,000 lbs unladen; heavier-duty trucks (and larger work trucks) exceed it.
- Not for resale — the buyer must purchase the vehicle other than to resell it. The statute doesn’t impose a strict “personal use only” test, so a personally owned work truck under the weight limit can qualify.
That makes Wyoming relatively favorable for light work trucks used in ranching and the energy sector — provided they’re under the unladen-weight cap.
When a work truck is excluded
If your truck exceeds 10,000 lbs unladen weight (or was bought for resale), you still have:
- Magnuson-Moss Warranty Act — covers the vehicle under its written warranty with fee-shifting; not limited by the unladen-weight cap.
- Consumer Protection Act — for misrepresentation at sale (actual damages only).
- UCC breach of warranty — Wyo. Stat. § 34.1-2-725 backstop.
Common commercial-vehicle defects
- Drivetrain — transmission and differential failures under load.
- Diesel — emissions/DPF/regen faults, fuel gelling, hard cold starts.
- Steering/suspension — death wobble; gravel-road and load-related wear.
- Brakes — heat and wear on grades and under load.
Bottom line
Wyoming’s lemon law reaches light work trucks under 10,000 lbs unladen weight bought other than for resale; heavier trucks fall to Magnuson-Moss and the UCC. Get a free case review.
