This leaflet explains what you need to know about driving as someone with diabetes. It covers potential risks such as having a hypo. This leaflet also includes the implications for your car insurance and the DVLA.


Diabetes does not mean you need to give up driving, but it does mean you have to plan in advance so your driving is safe and hazard free.

Car insurance

For your car insurance to be valid you must inform your insurance company as soon as you are diagnosed. This applies whether you control it by diet, tablets or insulin. If your company wants to charge you a higher premium, get quotes from other companies for comparison, as there can be a big difference.


Licence Categories

Group 1 Licence: cars/motorcycles/minibuses (up to 8 seats) up to 3.5 tonnes.

Group 2 Licence: Large goods vehicles and passenger carrying vehicles

Following a change in legislation implemented on the 15/11/11 anyone treated with insulin therapy can now apply for or renew their vocational entitlements to a Group 2 Licence (category C1, C1E, D1,D1E,CE,D,DE)

Drivers treated with Insulin 

If your diabetes is managed with insulin therapy you must by law inform DVLA by completing a Diab 1 form to apply for Car or Motorcycle licence.

Your license will be issued for 1, 2 or 3 years. There is no fee for renewal.

The following link provides information on driving recommendations for all types of Diabetes Treatment

You must tell the DVLA if you have or develop any problems that affect your safety to drive

  • Such as hypo at the wheel
  • Loss of hypo warning signs
  • Recurrent hypos
  • Diabetic complications

The following link details the application process for Group 2 Licence and qualifying conditions. If all criteria are met the Licence will be issued and reviewed annually. 

Drivers with diabetes treated by non insulin medication, diet, or both.

Group 1 Drivers do not need to tell the DVLA if their diabetes is treated by diet, tablets or both if they are free of the complications which are listed in the leaflet/link below. However it is still best to inform the DVLA

If you hold a Group 2 licence and you are prescribed a tablet which is a Sulphonylurea or prandial glucose regulator there is an increased risk of hypoglycaemia. Therefore you must notify the DVLA by completing medical questionnaire 'DIAB1V'.


Tablet Group Generic (proper) name Brand (trade) name
Sulphonylurea  Glibenclamide  
Gliclazide Diamicron/ Diamicron MR
Glimepiride Amaryl
Glipizide Glibenese/Minodiab
Prandial glucose regulator  Nateglinide Starlix
Repaglinide Prandin


If you are on any other diabetes treatment, including non-insulin injections such as Victoza or Byetta, it may not cause hypoglycaemia when taken on its own. However when used in combination with any of the tablets mentioned below, the risk of hypoglycaemia is greater.

If meets medical standards 1, 2 or 3 year licence will be issued.

DVLA Telephone: 0300 790 6801
