DVLA medical forms by condition

Short answerEach condition has its own DVLA form, and bus, coach and lorry drivers often use a different version. For example: epilepsy FEP1 (FEP1V for Group 2), insulin-treated diabetes DIAB1 (VDIAB1I), sleep apnoea SL1 (SL1V) and heart conditions H1 (VOCH1). Car and motorcycle drivers can report online instead. GOV.UK’s A to Z gives the form for every condition.

DVLA’s medical forms have short codes, a different one for each condition, and often another for lorries and buses. This page lists the form GOV.UK names for each of the nine conditions the kit covers, what else DVLA may send you or your doctor, and which application form goes with it when you reapply.

The forms, condition by condition

The form named on GOV.UK’s page for each condition, as the kit lists them (current as at October 2026).

DVLA’s A to Z, Health conditions and driving, covers many more conditions, and DVLA said in August 2026 that drivers can now check on GOV.UK how around 1,600 medical conditions may affect their driving. Forms change, so download the current one from the condition’s own GOV.UK page.

Reporting online or on a form

GOV.UK says you find out how to tell DVLA when you check whether you need to report your condition. If you have a car or motorcycle licence, you can report your condition online when you check it. If you have a bus, coach or lorry licence, you have to send a form or questionnaire to DVLA, and the address you need is on the form. If you’re not sure what to do, GOV.UK says to contact DVLA.

What DVLA may send you or your doctor

DVLA’s guide for medical professionals says its medical enquiries are generally a 2-stage process: first it asks you about the condition, by paper questionnaire or online; then it asks the relevant healthcare professionals, by questionnaire or by asking for medical notes. In some cases it needs an independent review by a DVLA-appointed doctor or optician, and some drivers need a driving assessment. GOV.UK adds that DVLA might contact your doctor or consultant, arrange for you to be examined, or ask you to take an eyesight or driving test.

The same guide says DVLA can’t make a licensing decision until all the relevant medical information is available and has been considered. So reply to every questionnaire promptly, keep copies, and ask your doctor or consultant whether DVLA has written to them and whether they’ve replied. Our guide to DVLA medical delays covers what else helps.

Forms for reapplying

When you reapply by post after a medical revocation or refusal, GOV.UK says you send the form for your health condition with an application form:

  • Car or motorcycle: a D1, from a Post Office that offers DVLA services. You must apply by post if your letter says you need to send medical evidence.
  • Bus, coach or lorry: a D2, plus a D4 medical report form if you’re aged 45 to 65 and haven’t sent one in the past 5 years. From 65 the licence is renewed each year with a completed D4.

Postal reapplications go to Drivers Medical Group, DVLA, Swansea, SA99 1TU. Our guides to reapplying and to DVLA medical addresses have the rest.

Words used in DVLA’s guide

The condition pages and DVLA’s guide use a few phrases that are easy to misread. The kit explains them like this:

  • “Must not drive” means stop driving.
  • “Must notify DVLA” means tell DVLA.
  • “Refused or revoked” means DVLA will not issue a licence, or will take it away.
  • “Relicensing may be considered” means DVLA can look at a new application. It is not a promise of a licence.
