The Daimler Roadliner was a single-deck bus or coach chassis built by Daimler between 1962 and 1972. Notoriously unreliable, it topped the 1993 poll by readers of Classic Bus as the worst bus type ever, beating the Guy Wulfrunian into second place. It was very technologically advanced, offering step-free access twenty years before other single deckers; as a coach, it was felt by industry commentators to be in advance of contemporary UK designs.
