The RAC emerged as the "Associate Section" of the Royal Automobile Club founded at the turn of the 20th century, and it was incorporated as R.A.C. Motoring Services Ltd. in 1978. It was sold by the members of the Royal Automobile Club to Lex Service Plc in April 1999, which subsequently renamed itself RAC Plc. In March 2005, RAC Plc was acquired by Aviva, and therefore delisted.
