A carriage is a two- or four-wheeled horse-drawn vehicle for passengers. Second-hand private carriages were common public transport, the equivalent of modern cars used as taxis. Carriage suspensions are by leather strapping or, on those made in recent centuries, steel springs. Two-wheeled carriages are usually owner-driven.

A horse-drawn vehicle is a piece of equipment pulled by one or more horses. These vehicles typically have two or four wheels and were used to carry passengers or a load. They were once common worldwide, but they have mostly been replaced by automobiles and other forms of self-propelled transport but are still in use today.
