Commercial Vehicles Under Maryland Lemon Law
Commercial-vehicle coverage under Maryland § 14-1501 — the 3/4-ton rated-capacity test, motor-home exclusion, and Magnuson-Moss alternative.
Larger commercial trucks face limited coverage under Maryland’s Lemon Law (§ 14-1501). Maryland defines a covered “motor vehicle” by registration class — passenger (Class A), motorcycle (Class D), multipurpose (Class M), and trucks (Class E) with a 3/4-ton or less manufacturer’s rated capacity. The cutoff is rated capacity, not a flat 10,000-lb GVWR, and motor homes are excluded entirely.
§ 14-1501 limits
- Trucks above 3/4-ton rated capacity fall outside the truck (Class E) definition.
- Motor homes — excluded entirely (no chassis carve-out).
- Fleet purchases of five or more vehicles — excluded.
Common vehicles outside the Class E truck definition
- Ford F-450, F-550, F-650/750 — well above 3/4-ton rated capacity.
- Ram 4500, 5500 — above the threshold.
- GM Silverado 4500HD, 5500HD, 6500HD — above the threshold.
- Cargo vans (Sprinter, ProMaster, Transit 350 HD) — varies by configuration.
Light-duty and 3/4-ton pickups (e.g., F-150, Silverado 1500/2500 rated at 3/4 ton or less, Ram 1500) generally remain within the Class E definition.
Alternative remedies for excluded vehicles
For trucks above the rated-capacity cutoff or motor homes:
- Magnuson-Moss Warranty Act — applies regardless of class or weight.
- UCC § 2-313 / § 2-314 — express + implied warranties.
- Maryland CPA — applies to many transactions (with some limitations).
Volvo Trucks Hagerstown
For heavy-duty commercial truck cases, Maryland hosts the Volvo Trucks Hagerstown powertrain plant — making Volvo Trucks a home-state defendant for heavy-truck cases (though § 14-1501 typically excludes these because they exceed the 3/4-ton rated-capacity truck definition).
Maryland commercial-vehicle market
- Port of Baltimore — Class I rail interchange, cargo logistics.
- I-95 corridor — freight movement.
- Federal agency fleets — DC-area government.
Bottom line
Maryland covers trucks only up to a 3/4-ton rated capacity and excludes motor homes entirely; heavier trucks fall outside § 14-1501. Magnuson-Moss + UCC + CPA remain available for those vehicles.
