Can You Drive an HGV with Diabetes? HGV Medical Requirements Explained

Being diagnosed with diabetes does not mean you must give up your career as an HGV driver. Yes, you can drive an HGV in the UK if you have diabetes. You must meet the DVLA’s medical requirements and hold the correct licence.

The rules for HGV and bus drivers are stricter than for car drivers if you’re on insulin. You have to prove to the DVLA that you have a condition that is under control and that you can manage.

They will also ask about your history of hypoglycemia, including your awareness and any complications. Being aware of the symptoms can help you prepare for your HGV medical.

This guide explains the DVLA’s diabetes requirements for drivers with an HGV with diabetes. It also covers different diabetes treatments and how to prepare for your HGV medical examination.



Can You Drive an HGV with Diabetes in the UK?

Yes, many people with diabetes should be able to drive an HGV in the UK. An HGV licence falls under group 2, which includes large lorries and buses.

The DVLA will consider whether your medical condition could impair your ability to drive a vehicle or put other road users at risk.

If you use insulin to control your diabetes, then you will need to notify the DVLA. Before you can get an HGV licence, you must show that you can monitor your blood glucose levels. You also need to understand the risks of hypoglycaemia (low blood sugar).

Having diabetes in itself does not mean you are disqualified from driving. However, passing an HGV medical does not automatically guarantee that the DVLA will issue or renew your licence either. Understanding the DVLA Group 2 medical requirements is an important part of diabetes and HGV driving.



How Does the Type of Diabetes Affect Your HGV Licence?

Type 1 Diabetes and HGV Driving

  • Monitoring of blood glucose levels: It is the responsibility of the driver to check and monitor their levels as and when required.
  • Knowledge of hypoglycaemia: Drivers must be aware of the symptoms and how to manage them.
  • Medical assessment: Attendance at specialist medical assessment and providing evidence when required by the DVLA
  • Eyesight: Meeting the eyesight requirements as set by the DVLA.

  • Oral or injected medication: The type of treatment being undertaken will decide what rules the DVLA will enforce.
  • Insulin treatment: Any driver with insulin-treated type 2 diabetes should follow the guidance for Group 2 drivers dealing with insulin.



Diabetes Treated with Insulin or Other Medication

  • Insulin: You will need to pass specialist tests and have blood glucose monitoring as part of a DVLA Group 2 medical assessment.
  • Sulphonylureas and glinides: You must satisfy the appropriate medical standards and notify the DVLA if you’re taking these medicines, which can cause low blood sugar.
  • Other medicines such as metformin: These are associated with a lower risk of hypoglycaemia when used on their own. But you must still satisfy the relevant Group 2 requirements.

  • Validity: If you satisfy the requirements above, your Group 2 licence with insulin treatment will be valid for one year at a time.

  • Check your blood glucose at least twice daily (including days when you’re not driving).

  • You should know the symptoms of blood sugar.

If you have an episode of severe hypoglycaemia, you will need to stop driving and follow the DVLA’s instructions.

 

Can You Get or Renew an HGV Licence If You Have Diabetes?

 

The short answer is yes, but there are some conditions.

  • New applications: You will need to take a Group 2 medical to prove you are fit to drive.
  • Licence renewals: You will be required to continue to meet medical requirements, and any change in your condition or treatment should be reported to the DVLA
  • Changes in your health: Severe hypos, new complications or changes to your medication may require further medical information.
  • Initiation of insulin: You must stop driving Group 2 vehicles until the DVLA confirms the status of your licence. These requirements are important to understand when applying for an HGV licence with diabetes.

How Can You Prepare for an HGV Medical with Diabetes?

  • Speak to a diabetes specialist: Beforehand, speak to a diabetes specialist and ask them if there are any additional medical records that they think you may need to provide for your application.
