The DAF LF is a range of light/medium duty trucks produced by the British manufacturer Leyland Trucks.It is a redevelopment from the Leyland Roadrunner of 1984.
The LF45 and LF55 are powered by Cummins B Series engines. The distribution truck and pickup versions of the LF45 use the 4 cylinder, LF45s with powered equipment such as bin lorries and vacuum tankers use the 6 cylinder, and all LF55s use the 6 cylinder due to their increased size and weight. The LF shares its cab design with the Renault Midlum and the Volvo FL. It is also the base for medium duty trucks for Kenworth and Peterbilt.
The LF won the International Truck of the Year 2002 award.
