What it means in plain English
The D4 medical is one of the process terms that makes C1 feel more complicated than it needs to. In simple terms, it is the medical part of checking fitness for a larger-vehicle licence route.
Learners often ask about it alongside provisional entitlement, theory tests and package pricing.

Why it matters for C1 learners
Medical fees are included in the C1Licence.co.uk package prices, so explaining the term helps users understand what is included.
It also prevents the medical stage from feeling like a hidden extra or a surprise later in the process.
Common confusion
The medical stage is separate from practical training.
If the medical is already complete but theory is not, the package position should be checked with the team during enquiry.
