There are extra rules for people with diabetes who want to drive. This is to make sure it’s safe for you and others. This information is about what to tell your driving licensing authority when you have diabetes.

Driving larger vehicles with a Group 1 license
We’ve campaigned for years to make sure the law is fair. So that you can carry on driving – as long as you’re taking the right steps to stay safe at the wheel.
The rules differ depending on what vehicle you want to drive:
- To drive a car or motorbike, it’s called a Group 1 driving licence.
- To drive a bus or lorry, it’s called a Group 2 driving licence – the laws are a lot stricter.
The rules are complicated, so use the tables below to find the information you need. If you understand the rules, you’ll know when to contact your relevant driving licensing authority and why.
If you live in England, Wales or Scotland, it’s the Driver and Vehicle Licensing Agency (DVLA) who look after the rules on driving.
If you live in Northern Ireland, it’s the Driver and Vehicle Agency. To make things easier, we’re going to use DVLA throughout this information.
They both have the same rules, but the DVA only uses paper forms, while the DVLA has everything online too.
When you're applying for your provisional licence, there will be a part on the form to fill out about your diabetes. Make sure you don't wait until you have passed your driving test to tell the DVLA or DVA about your diabetes.
If you are at risk of hypos when you have your driving lessons, it's a good idea to tell your driving instructor that you have diabetes as you'll need to check your blood glucose levels before you drive.
Provisional licenses and booking your driving theory test
If you have already been diagnosed with diabetes and take insulin, you will need to declare diabetes as a medical condition when you apply for a provisional license. The rules are the same as those for a group 1 driving license.
Before you can take the practical driving test, you will have to take and pass a theory test. Like any formal exam, there are strict rules about what you can take with you, and this includes diabetes tech. But it's important that you can continue to monitor your blood sugars and treat your diabetes, if needed, during the theory test.
The Driving Vehicle Standards Agency (DVSA) support people with diabetes to do this. But they need to know about your diabetes and any tech you use when you book the theory test. This is so arrangements can be made at the test centre. If you arrive for the test without having requested support, you will not be able to use your diabetes tech during the test. If this means cancelling, you'll have to re-book and pay for another one.
This applies to anyone who uses an insulin pump or CGM with a mobile phone or reader to manage their diabetes. Smart watches must be removed for a theory test so you'll need your phone or reader if you usually use a smart watch to monitor your blood sugar levels.
You will have to provide the DVSA with evidence that you have diabetes and are using diabetes tech. This evidence must:
- Show your first and last name and confirm you have diabetes
- Be a letter, on headed paper, an email, diagnosis or medical report
- Be from a doctor or other medical professional
This evidence can be uploaded as part of the online test booking process or it can be submitted later by email or post.

Booking your theory test
How to book
To book your theory test online, go to this gov.uk webpage. Once you have selected "Start Now", you'll see a screen called 'Get the right support during your theory test'. You should select "Yes" at the bottom of the page to the question "Do you need support for your theory test?". On the next page select "Continue and get support"
You will then be taken through a few screens collecting basic information about you and be asked what type of theory test you need support for - car or motorcycle.
The next screen will ask 'What test support do you need?' and you should select the box "Use my monitoring device for a medical condition."
This opens up the screen titled 'Do you use a monitoring device to manage a medical condition?'. Select "Yes, I need a monitoring device" which opens a text box where you can provide details of any devices you use. It is recommended you give details of all the equipment you think you may need.
The next page explains what sort of evidence is needed to support your request followed by screens that take you through the process of selecting a test centre and dates. Once these screens are completed, you'll be able to upload your evidence if you have it ready. You'll also be told how to send the evidence by post or email if you prefer.
It normally only takes a few days for the DVSA to review and approve the evidence. But it also takes time for them to get information from the Test Centres before you can be offered dates and times for the test. If evidence provided is not suitable, DVSA will contact you by email requesting further evidence.
Once the evidence is approved and available dates and timeslots confirmed, the DVSA will contact you by email with details of how to book and pay for the theory test. When you have done this, you should see a theory test booking confirmation screen which includes your booking reference. We recommend you print a copy of this page and take it along to the test centre on the day of the test.
You can contact our Helpline team on 0345 123 2399 or helpline@diabetes.org.uk if you have any further questions about your diabetes and completing your booking.
What to expect at the test centre
The DVSA gives guidance to test centre staff to help them treat people who use tech to manage their diabetes appropriately. If you have followed the booking route above and received confirmation from the DVSA that support will be provided, this is what you can expect from the test centre:
- Everybody will undergo security checks before entering the testing room. Staff will look at any diabetes tech you're using but should not touch it or ask you to remove it. We have worked with the DVSA and provided pictures of commonly used diabetes tech, so test centre staff should have some familiarity with what it looks like.
- Your test should be in a separate room with an invigilator who'll be responsible for looking after your mobile phone, or reader during the test. They should be in the room for the whole test, and you can raise your hand if you need to use your equipment. You should be allowed to take an unscheduled break to check your blood sugars. You should also be given extra time to complete the multiple-choice part of the theory test. This should mean you'll have plenty of time to test blood sugars and treat a mild hypo, if necessary, without it affecting the time available to do the test.
- You will also be allowed to have some hypo treatments in the room with you. This may include sugary sweets, small cartons of fruit juice, non-diet drinks or glucose tablets. The test centre staff may ask to inspect the packaging of any hypo treatments you want to take into the test room.
DVLA rules for people with diabetes
They look at your fitness to drive based on how you treat your diabetes and if you have any diabetes complications.
It’s really important that you follow these rules as soon as they start applying to you. For example, you should stop driving and contact the DVLA as soon as you find out you have to take insulin for the long term or if you start to develop complications. If you don’t, you’re breaking the law.
In all cases, if you have one severe hypo at the wheel you must stop driving and tell the DVLA straight away.
Use the tables below to find the information you need so you can drive safely.
Driving a car or motorbike (Group 1) and severe hypos
A severe hypo is one where you need help and can’t treat it on your own. This is different from having a regular hypo.
"A friend came around and found me unconscious. I was having a really bad hypo. I ended up having to go to hospital" - Mim
More than one severe hypo while awake (when you’re not driving)
If you have more than one severe hypo while awake in 12 months you must stop driving and tell the DVLA. Your licence will be revoked but you can apply again after three months. See your healthcare team to get their advice on your diabetes treatment and management to cut down the risk of this happening again.
To be clear, this is about more than one severe hypo when you’re not driving. If you have even one severe hypo while driving, you must stop driving and tell the DVLA straight away.
A severe hypo while sleeping
The law about severe hypos while sleeping changed for Group 1 licences (cars, motorbikes) after we campaigned for the DVLA to recognise they aren’t a risk for driving. You can’t take the same steps to treat them that you can when you’re awake, so it wasn’t fair.
The DVLA now say you don’t need to tell them if you have a severe hypo while you’re asleep.
It isn’t the same for Group 2 licences (for large vehicles and lorries). You can’t drive with a Group 2 licence if you don’t have full hypo awareness or you’ve had one severe hypo in the last year. If you have a severe hypo at any time, you must stop driving and tell the DVLA.

In all cases, you must tell the DVLA if you have a pancreas or islet transplant or any diabetes complications.
If you haven’t told the DVLA about your diabetes
This can happen if your healthcare team doesn’t tell you that your diabetes, or the way it’s now being treated, affects driving.
If you’re not sure, check the DVLA Summary for a Group 1 Licence or the DVLA Summary for a Group 2 Licence or go to the DVLA directly.
If you’ve carried on driving without telling them when you needed to, you’ve broken the law. Your insurance could be invalid, you could be fined and if you’ve had a collision you could be prosecuted. So if you’ve got any doubts at all, ask your healthcare team or call our helpline to get advice straight away.
If you lose your Group 1 licence
What happens next depends on why it was revoked.
"I knew the rules. Having two hypos and not one hypo means you need assistance. It was a massive shock to lose my licence. I called the Diabetes UK helpline, and they followed through with everything they said they were going to do. Six weeks after coming out of hospital, I got my licence back." - Mim
You had more than one severe hypo while awake in 12 months
It doesn’t matter if you weren’t at the wheel at the time, you’ll still have your licence taken away and the DVLA will need to decide if it can be reissued. The DVLA won’t start to look into this until three months have passed after the last severe hypo.
You had a severe hypo at the wheel
If you’ve had a severe hypo while driving, you’ll probably lose your licence because the DVLA will say you don’t have good enough hypo awareness to drive safely. You must let them know straight away.
If you have a collision or are seen to be driving badly and it’s spotted by the police or they’re called out, then your licence will be revoked – if they find you had very low blood sugar at the time.
To get your licence back, your healthcare team will need to support your reapplication. The DVLA will need to be satisfied that it happened because of something unusual and that it probably won’t happen again. They’ll need to know that over a period of at least three months (it could be longer), you didn’t have another one and that your blood sugar levels have been good.
What if your blood sugar level drops after a collision?
This can happen—particularly if you’ve been in an incident and you had to wait for the emergency services to arrive. So you didn’t have time (or weren’t able) to treat the start of a hypo.
You could lose your licence unless you can prove that your blood sugar levels weren’t low at the time it happened, so didn’t cause it.
It helps if you can show that your blood sugar readings weren’t dangerously low before the incident. So although you don’t need to have a meter with a memory to hold a normal driving licence, it can help here as it can prove that you’d been testing at times relevant to driving —and that your blood sugar levels were OK within 2 hours before the accident.
If an ambulance is called, the paramedics fill out a report giving the results of any tests, like a blood glucose test. There’s also a section on what they think of your level of consciousness. If you can answer questions normally, they should note this down and it can be helpful to your case. Their report also shows the time help was called and so how long you may have had to wait for treatment following a shock. This all helps, so make sure and ask for a copy of the ambulance report to show the DVLA.
If the police arrived first, you could ask them for a report that says what time they were called and what was said between you. Again, this could help prove to the DVLA that there was some time between the shock of the incident and when you were able to treat your diabetes.
Call our Helpline if you want more advice on any of this.
Driving larger vehicles with a Group 1 licence
Older, paper licences used to be issued with entitlements showing that the driver could drive (or tow) some larger vehicles.
But if you’re now on a medically restricted licence, it won’t allow you to drive the same types of vehicle that were on your old paper licence.
If you want to drive these larger vehicles, you’ll need to apply for a Group 2 licence which will be stricter.
Towing a trailer or caravan
The rules around this can seem complicated and can depend on when your licence was issued. It’s best to get in touch with DVLA.
Driving a minibus
Again, the rules around this can seem complicated and it’s best to go direct to the DVLA.
For example, it can depend on whether you’re being paid to drive the minibus and it can depend on when your licence was first issued. Check with the DVLA.
Driving a taxi
If you’re in Northern Ireland, you apply for a taxi licence through the DVA. The licence has similar rules as a Group 2 Licence.
In England, Scotland and Wales, you need a Group 1 licence to drive a car-sized taxi but you’ll also need to apply to your local taxi licencing authority. They will have stricter rules similar to those for a Group 2 licence.
Driving emergency vehicles
It’s now up to the service (police, fire or ambulance) in your area. They have their own rules about whether you can drive an emergency vehicle if you take insulin.
The DVLA’s statement on this says that their rules are the same as they are for all drivers with Group 1 or 2 licences. But the service in your local area can decide if it needs to be stricter. It’s down to them.
This means that for larger vehicles, like a fire engine, you’ll probably need a Group 2 licence but it’s up to your employer to risk assess the role. Then they need to risk assess you and decide if it’s safe for you to do the job.
So, in some areas of the country the local emergency services will have extra rules for drivers of emergency vehicles treating their diabetes with insulin. It’s to make sure they’re as safe as any other driver and to avoid discriminating against people with diabetes who can meet the standard.
