A carriage is a private four-wheeled vehicle for people and is most commonly horse-drawn. Second-hand private carriages were common public transport, the equivalent of modern cars used as taxis. Carriage suspensions are by leather strapping and, on those made in recent centuries, steel springs. Two-wheeled carriages are informal and usually owner-driven.
Coaches are a special category within carriages. They are carriages with four corner posts and a fixed roof.
Two-wheeled war chariots and transport vehicles such as four-wheeled wagons and two-wheeled carts were forerunners of carriages.
In the twenty-first century, horse-drawn carriages are occasionally used for public parades by royalty and for traditional formal ceremonies. Simplified modern versions are made for tourist transport in warm countries and for those cities where tourists expect open horse-drawn carriages to be provided. Simple metal sporting versions are still made for the sport known as competitive driving.
