UK driving theory test glossary — 55 terms

Executive agency of the Department for Transport that carries out theory and practical driving tests in Great Britain, approves driving instructors and MOT testers, and runs roadside enforcement of drivers and vehicles.

DVSA owns the theory-test syllabus, question bank and pass marks used across England, Scotland and Wales.

Executive agency of the Department for Transport responsible for issuing driving licences, registering vehicles, collecting Vehicle Excise Duty and maintaining the GB driver record.

DVLA holds the endorsement record; DVSA conducts the tests — frequently confused.

Executive agency of Northern Ireland’s Department for Infrastructure responsible for driver and vehicle licensing, vehicle and driver testing, and roadside enforcement across Northern Ireland.

Northern Ireland sits outside DVSA’s remit; NI learners take DVA theory and practical tests with separate fees and rules.

Two predecessor agencies merged on 1 April 2014 to form DVSA. The DSA ran driver testing and set driver-training standards; VOSA ran vehicle roadworthiness and enforcement, with its operator-licensing function passing to the Traffic Commissioners for Great Britain.

Older guidance, app reviews and forum posts still reference DSA — treat it as the same body as today’s DVSA.

Unit inside the Department for Science, Innovation and Technology that builds and runs the gov.uk platform and shared digital services used across UK government departments.

GDS runs gov.uk and GOV.UK One Login, the platform that fronts the DVSA theory-test booking journey; the underlying booking and sitting infrastructure is delivered by DVSA’s FTTS contractors.

DVSA’s current theory-test delivery programme, procured under a 2019 competitive-dialogue tender as three regional Lots and delivered by Pearson VUE (Pearson Professional Assessments) and Reed in Partnership through September 2028.

When a candidate books a UK car or motorcycle theory test today, the booking and sitting infrastructure is operated under the FTTS contract.

Component of the FTTS programme covering the network of physical theory-test centres across Great Britain and Northern Ireland, packaged as three regional Lots — Region A, Region B and Region C — under contracts let by DVSA, with the Region A contract also serving Northern Ireland’s DVA.

Qualified instructor on DVSA’s official register — the only category of instructor legally allowed to charge for car driving lessons in Great Britain.

All paid car lessons leading up to the theory and practical test must be delivered by an ADI (or a trainee under ADI supervision).

Person training to become an ADI who has passed ADI Part 2 and holds a 6-month trainee licence allowing supervised paid instruction before sitting ADI Part 3.

DVSA forbids the term “PDI” in public-facing advertising — trainees must describe themselves as a “trainee driving instructor”.

Video-clip section of the DVSA theory test that scores a candidate’s reactions to 15 developing hazards across 14 clips, with up to 5 points per hazard for early detection.

Sat in the same sitting as the multiple-choice section. Pass mark is 44 out of 75; both sections must be passed together.

Score needed to pass the car theory test: 43 out of 50 multiple-choice questions in 57 minutes, plus 44 out of 75 on the hazard perception clips, in the same sitting.

Equivalent to 86% on multiple-choice — a high bar that catches out a large share of first-time candidates.

Statutory two-year window during which a passed DVSA theory test certificate remains valid for booking a practical driving test; expires exactly 2 years after the pass date with no extension.

Must be passed before booking Module 2. Both modules sit under the same 2-year theory-test certificate window.

Five-step learner observation routine — Mirror, Signal, Position, Speed, Look — taught in DVSA driver-training practice and applied to any change of direction at speed, including lane changes, overtaking and junction approaches. It extends the Highway Code’s three-step Mirrors–Signal–Manoeuvre sequence (Rule 161) by breaking the manoeuvre itself into position, speed and a final look; each step is sequenced and should not be skipped.

Tested in theory-test wording and central to the practical observation requirement.
