What defines a trailer according to Missouri regulations?

A trailer, according to Missouri regulations, is defined as a vehicle that does not have its own motor power and is specifically designed for the purpose of carrying property or passengers. This aligns with the general understanding of a trailer as an attachment that is towed behind a vehicle, such as a truck or SUV, rather than one that operates independently.

The significance of this definition is that it differentiates trailers from motor vehicles. Motor vehicles, which are often equipped with their own engines, are designed to transport cargo or people without relying on another vehicle. The requirement for a trailer to be non-motorized emphasizes its role in auxiliary transport rather than as a stand-alone means of movement. This classification is essential for registration, safety inspections, and adherence to regulations governing the use of such vehicles on public roads.
