What is the D4 medical certificate and how do I record it?

Right, let's sort out those D4 medical certificates. This is a big one for Group 2 drivers, and auditors always have an eye on it.

The D4? That's the DVLA medical examination report. Every Group 2 (HGV/PSV) driver needs one signed off by a registered doctor when they're first applying for or renewing their entitlement. It's non-negotiable.

Heads up — the schedule for these is pretty strict:

  • Initial application: Always needs a D4.
  • Renewal at age 45: D4 required, then every 5 years after that.
  • From age 65: You'll need a D4 annually.

Quick one — once signed, a D4 is only valid for 4 months before it needs to be submitted to the DVLA. Don't let that window close on you.

Recording a D4 in DDIR

Now, getting this recorded in DDIR is nothing to it, across any tier (A, B, or C). Here's the drill:

  1. Jump into Driver Compliance and head over to the Medical tab.
  2. Find your driver and hit "Edit" on their row.
  3. Fill in the crucial details: the issue date, expiry date, the examiner's name, and their GMC number. Accuracy here is key.
  4. Got a scan or a photo of the certificate? Upload it right here – it's optional but always a good move for your records.
  5. Don't forget to set the Section 88 status. You'll pick from 'normal', 'renewal in progress', or 'revoked on medical grounds'.
  6. Hit Save, and you're all set.

This is where DDIR really earns its keep. We'll flag drivers as Critical if their D4 has expired, and give you a Warning when it's due to expire within 28 days. That means no need for endless questionnaires; your risk dashboard shows you exactly what you need to know, instantly. Fire prevention beats fire fighting, right?

Keeping on top of D4s is a breeze when DDIR does the heavy lifting, ensuring you stay compliant without breaking a sweat.
