The Driver Was Part of the Team

A postilion controlled a coach from horseback, riding one of the horses harnessed to pull it rather than sitting on the coach. From that position, the rider could handle the reins close to the animals and guide the team as it moved. The horse beneath the postilion was both a source of pulling power and the rider’s moving platform.

Why Ride Instead of Sit?

A coach’s front seat, or box, did not have to serve as the driver’s place. Keeping the driver on a horse left that space available for passengers or luggage and made the arrangement useful on journeys where a mounted driver was preferred. It also put the postilion among the horses, where the team’s pace and direction could be managed directly rather than from behind the harnessed animals.

The arrangement made the distinction between vehicle and team unusually visible: the person guiding the coach traveled on the same animals that supplied its power. In a postilion-driven coach, the driver was not above the team but riding within it.
