The Glucose Never Lies® Podcast
Host John Pemberton — diabetes educator, researcher, and dad living with type 1 since 2008 — explores how to think clearly about type 1 diabetes in the real world.
EACH episode translates current evidence and expert practice into decisions you can use: CGM accuracy and interpretation, getting more from pumps and automated insulin delivery, movement as a glucose tool, nutrition that protects performance and enjoyment, sleep, travel, parties, and sport.
Guests include leading clinicians, researchers, and people with lived experience. Expect respectful challenge, plain language, and practical take-aways.

Episode Overview
Driving with type 1 diabetes is not just about safety. It comes with clear legal responsibilities.
We cover:- The legal differences between Group 1 (cars, motorcycles ≤3.5 t, ≤8 passengers) and Group 2 (HGV, minibuses, passenger vehicles >3.5 t or >8 passengers).
- Why the law requires you to be ≥5 mmol/L before driving (“5 to drive”).
- The 45-minute rule: after treating a hypo, you must wait 45 minutes once you are back above 5 mmol/L.
- When CGM readings are accepted (Group 1) versus when only finger-prick testing counts (Group 2, currently).
- The importance of self-declaring severe hypoglycaemia: two daytime events in 12 months means you must report it.
- Practical tips: keeping your meter’s date/time accurate, carrying a backup meter, and setting CGM low alerts at 5 for long journeys.
Key Takeaways- 5 to drive: ≥5.0 mmol/L
- 4.0–4.9 mmol/L: snack, then drive
- <4.0 mmol/L: treat → confirm >5.0 → wait 45 minutes once above 5
- Check every ≤2 hours — each check “expires” like a parking ticket
- Group 1 drivers: CGM or finger-prick both accepted
- Group 2 drivers: finger-prick only (until law changes)
- Severe hypos: two daytime events in 12 months → you must self-declare
- Responsibility lies with the driver, not your clinician
