Yes, you can get an Irish learner permit if you have diabetes, including type 1 on insulin. If you are treated with insulin, or with tablets that can cause hypos (such as sulphonylureas), you must tell the NDLS when you apply, and your doctor completes a D501 medical report. For a car (Group 1), you must have had no more than one severe hypo needing another person’s help in the last 12 months, have good hypo awareness, and check your glucose at times relevant to driving. If you meet the standard, a licence of 1 to 3 years may be issued.
These rules come from Sláinte agus Tiomáint, 13th edition, April 2026. Your diabetes team is the right source for treatment advice.
Do you need to tell the NDLS?
| How your diabetes is treated | Tell the NDLS? |
|---|---|
| Insulin | Yes, when applying or renewing |
| Tablets that can cause hypos (sulphonylureas, glinides) | Yes, same rules as insulin |
| Other tablets, or non-insulin injectables | No, unless diabetic eye problems affect your sight or field of vision |
| Diet alone | No, unless diabetic eye problems affect your sight or field of vision |
| Temporary insulin (for example gestational diabetes) | Only if you have disabling hypos, or treatment lasts more than 3 months (or more than 3 months after delivery) |
The form side, including which box to tick and who completes the D501, is in Medical and eyesight requirements for an Irish learner permit.
The Group 1 standard if you use insulin
- No more than 1 episode of hypoglycaemia needing another person’s help in the preceding 12 months.
- Appropriate awareness of hypoglycaemia.
- An understanding of the risks of hypoglycaemia.
- Glucose monitoring at times relevant to driving.
- Regular medical review.
- No other disqualifying complication, such as a visual field defect.
If you meet the standard, the guidelines say a 1 to 3-year licence may be issued.
Recurrent severe hypos and impaired awareness
- Recurrent severe hypoglycaemia (more than one episode needing help in 12 months): a licence is not issued or renewed unless supported by a specialist in endocrinology and diabetes and regular medical assessment. For recurrent severe hypos while awake, not until at least 3 months after the most recent one.
- Impaired awareness (no warning symptoms at all): you must not drive once this is confirmed. You can drive again when your consultant or GP reports that awareness has returned.
- You must tell the NDLS if you have more than one severe hypo needing help within 12 months.
- Continuous glucose monitors: you may use one to check your glucose for driving a car, but you must also carry finger-prick testing kit. Confirm with a finger-prick reading if the monitor shows 4.0 mmol/L or below, if you have hypo symptoms, or if the reading does not match how you feel. An alarm does not replace your own awareness of a hypo. If you become reliant on alarms to recognise one, stop driving, contact your diabetes team and notify the NDLS.
Before and during every drive
The NDLS diabetes-and-driving leaflet currently linked by the HSE advises:
- Carry your meter and strips, and ID showing you have diabetes.
- Check before driving and every two hours while driving.
- 5.0 mmol/L or less: have a snack. Below 4.0 mmol/L, or if you feel hypo: do not drive; treat it and retest to make sure you are above 5.1 mmol/L.
- If a hypo starts while driving: stop as soon as it is safe, switch off, take the keys out and move out of the driver’s seat. Do not drive until 45 minutes after your glucose has returned to normal.
- Keep fast-acting carbohydrate within reach in the car.
- Take regular meals, snacks and breaks at least every two hours on long journeys, and avoid alcohol.
The guidelines point out that driving on after you become aware you are not fit to drive is an offence.
Tips for EDT lessons and the test
- Build a glucose check into the start of each lesson, and tell your instructor you will stop if you need to.
- Keep your meter and glucose in the instructor’s car, not just your bag.
- On test day, check before you leave and again before the test, and allow time to wait out a low.
- Diabetes can affect eyesight. The NDLS leaflet recommends a full eye test at least every year.
