Enforcement & standards
What was the DSA (Driving Standards Agency)?
The Driving Standards Agency was responsible for driver testing and driver training standards in Great Britain until 2014, when it merged with VOSA to form DVSA. Its work — the driving test, the theory test, Driver CPC — now sits with DVSA.
DSA was the driver side and VOSA the vehicle side. The merger put both under one agency, which is why DVSA today both tests your lorry and examines the person driving it.
For an operator the part that survives most visibly is Driver CPC: the periodic training requirement for professional drivers, administered under DVSA since the merger.
The name appears in older driver records and training certificates. Those remain valid — a qualification is not invalidated by the awarding body being renamed.
What goes wrong in practice
- Assuming a certificate issued under the DSA name needs reissuing. It does not.
- Looking for current driver testing requirements under the old agency name.

- Driver CPC, explained: the 35-hour rule that keeps a licence validProfessional LGV and PCV drivers need 35 hours of periodic training every five years — miss the deadline, and the right to drive commercially lapses, regardless of how experienced the driver is.
- VOSA: what happened to it, and who does its job nowVOSA was abolished on 31 March 2014 and its work passed to DVSA the next day. The name survives in the trade and in a great many operator handbooks — and the enforcement it ran then looks nothing like the enforcement you meet now.
