An HGV driver with type 2 diabetes has an HbA1c of 69 and a falling kidney function; the drug that helps his kidneys is not the one he is worried about.
Candidate brief

Persona and manner
- Warm, proud of his job, a little defensive about his health; talks about the road and his grandchildren; not keen on 'more tablets'.
- He has heard from a driver mate that 'the new diabetes tablets' cause 'water infections' and that if he 'goes hypo' he loses his licence.
Opening line — say this verbatim
- "The nurse said my sugar's crept up and my kidneys aren't what they were. I'll be honest, doctor — I'm 61, I've got four years left on the lorries, and I need to keep my licence. What are we looking at?"
Volunteer freely if given the space
- Long shifts, motorway food, 'a coffee and a pastry keeps me going'; eats one big meal at night.
- Has 'never had a hypo'; checks his sugar 'when I remember' — the DVLA meter is in the cab.
- Feels well; a bit more tired; up once or twice at night to pass urine.
Only if asked
- Glucose checks: DVLA requires testing at least twice daily and within two hours before driving; he does 'most days' but not always before every shift; readings 'seven to twelve'. Never below four that he has seen.
- Has had two 'funny turns' — sweaty and shaky mid-afternoon after skipping lunch — settled with a chocolate bar. Did not check glucose. Has not told anyone.
- Takes his tablets 'most of the time'; misses gliclazide when he forgets lunch because 'that's when the shakes come'.
- Weight up half a stone in a year. No chest pain; no breathlessness; no foot problems; vision 'fine with glasses'.
- Declined vaccines because 'I don't like needles and I never get ill'.
- Family: wife works in a school; two grown children; four grandchildren he 'lives for'. Retirement at 65 planned, pension depends on it.
- He will accept a tablet 'if it doesn't get me hypos and doesn't cost me the licence'.
Ideas, concerns and expectations
- Idea: 'I just need to try harder with the diet.'
- Concern: losing the Group 2 licence; the mate's story about 'water infections'; needles (insulin).
- Expectation: to be told what to change and reassured about the licence.
Cues to deliver, timed
- Minute 2: 'I've got four years left on the lorries.'
- Minute 4: 'a couple of funny turns, but that's just missing lunch' — dismissive, only if asked about hypos.
- Minute 7: 'is that the one that gives you water infections?' — if an SGLT2 inhibitor is proposed.
How to respond to the doctor's plan
- If the doctor recognises the two afternoon episodes as probable hypoglycaemia, explains the DVLA Group 2 rules (twice-daily and pre-driving testing; a severe hypo or impaired awareness means notification and licence review; sulphonylureas are permitted only with proper monitoring), proposes an SGLT2 inhibitor for kidney and heart protection with honest advice on genital thrush, hydration and sick-day rules, reduces or stops gliclazide to remove the hypo risk, checks metformin at his eGFR, addresses blood pressure and lipids, offers vaccinations and a diet plan that fits shift work, and books review with bloods in 3 months: relieved — 'so the new one's actually safer for my licence than the old one?' — and agrees.
- If the doctor simply increases gliclazide: 'and the hypos?' — then accepts; the examiner will not.
- If the doctor raises insulin: 'no way, not with the licence' — and disengages unless the doctor explains it is not being proposed.
Examination findings if requested
- BP 148/86; weight 101 kg; feet: pulses present, sensation intact; no oedema; capillary glucose now 9.8.
Do not
- Volunteer the funny turns, the missed pre-driving checks or the pension unless asked.
- Refuse everything; he is persuadable by 'safer for the licence'.

Global rating guide: Pass = hypoglycaemia recognised, SGLT2 inhibitor started and gliclazide de-escalated, DVLA Group 2 rules accurate, cardiovascular risk addressed, review booked.
Teaching points
- NICE NG28 (2022): offer an SGLT2 inhibitor to people with type 2 diabetes and CKD with ACR >30 mg/mmol; consider if ACR 3–30 — here eGFR 52 with ACR 6.2, plus established cardiovascular risk, supports it. Metformin continues to eGFR 30.
- DVLA Group 2 (bus/lorry) with sulphonylureas or insulin: glucose testing at least twice daily and within two hours before driving, recorded on a memory meter for three months; any severe hypo in the previous 12 months, or impaired awareness, disqualifies. Sulphonylurea hypos are the commonest reason drivers lose Group 2 licences.
- The mate's story (SGLT2 inhibitors and genital infection) is a belief to answer with numbers, not dismiss: about 1 in 10 women and 1 in 30 men; treatable; hydration and hygiene advice.
