Plain-English definitions

Short explanations for learners who are new to C1, not jargon written for people already inside the licence system.

Clear onward routes

Each term points you towards the most relevant training, pricing, vehicle-use and process pages.

Answers to specific questions

Use the glossary when you need a quick answer without digging through a full training page.

Start with the terms learners ask about most

The glossary is designed as a support layer for the main site. It helps people understand what a term means before comparing training packages, checking whether they already have C1 or deciding whether their vehicle falls into the C1 category.

  • Category C1
  • Maximum Authorised Mass (MAM)
  • Plated weight
  • Gross Vehicle Weight (GVW)
  • Provisional C1 entitlement
  • D4 medical
  • C1 theory test
  • Hazard perception test

How the glossary helps the C1 journey

A learner researching a motorhome may need to understand MAM. A student paramedic may need to understand provisional C1, medical and theory stages. A 7.5 tonne driver may need to separate C1 from Category C or Driver CPC. These pages give each term a clear home.
