"The Driver and Vehicle Standards Agency will replace the Driving Standards Agency (DSA) and the Vehicle and Operator Services Agency (VOSA) with responsibilities for setting, testing and enforcing driver and vehicle standards in Great Britain.
There will be a gradual introduction of the new agency name ahead of the formal launch in April 2014, with no change to the level or quality of services during the transition period.
