For example, the lemon laws in Indiana, Vermont, Wyoming and Louisiana exclude from coverage vehicles weighing more than 10,000 pounds. Some states set out long lists of excluded vehicles. If your vehicle isn't explicitly excluded, you can argue the lemon law in fact covers your vehicle. For example, Connecticut courts apply the lemon law to motorcycles even though the statute doesn't expressly mention motorcycles. One way to justify this approach is that because the legislature was so specific in defining the excluded vehicles, all other vehicles should be considered covered by the statute.
Lemon laws are remedial in nature, and courts often interpret such laws very broadly.
Under the objective standard the court looks at whether a vehicle is normally used or primarily designed for a consumer purpose. The court will apply the lemon law protections if the vehicle is normally used or primarily designed for a consumer purpose. Under the objective standard the court will probably not apply lemon law protections to buses, large trucks and similar vehicles that are almost always purchased solely for business use. The legislative trend is to include the motorized portion of motor homes, while excluding the living quarters or non-motorized portion of the vehicle. That is, if the defect relates to the motorized portion, the consumer is entitled to a new motor home or a refund on the complete purchase price.
