DAC, short for Diesel Auto Camion, is a Romanian truck brand produced since the 1970s in the Braşov area. Since 1990 DAC has been the special trucks division of Roman trucks.
DAC was established after World War II on the foundation of the old ROMLOC automotive factory built in 1921. In the spirit of the communist days, the industrial plant was named Steagul Rosu (the Red Flag). As of 2000 almost 750,000 trucks had been produced.
DAC trucks share the same construction platforms with the Roman trucks but it was not part of the 1971 venture between the then-West German company MAN and the Romanian government.
