Understanding What Happens If You Fail an HGV Medical Exam in the UK? For HGV drivers in the UK, the Medical Examination is a Non-Negotiable Step.
At Precision Driver Medicals, we provide professional and DVLA-compliant HGV medical exams. If you fail your HGV medical exam, understanding the following steps can help you navigate the process smoothly.

Reasons for Failing an HGV Medical Exam
Several medical conditions can lead to a failed HGV medical exam. These include:
- Poor eyesight – If your vision does not meet the required standard, even with corrective lenses.
- High blood pressure – If your blood pressure is too high and unmanaged, it may disqualify you.
- Diabetes – Uncontrolled diabetes, particularly if it leads to hypoglycemia, can be a concern.
- Neurological disorders – Conditions such as epilepsy or severe migraines.
- Heart conditions – Issues like arrhythmias or a history of heart attacks may impact your fitness to drive.
- Mental health conditions – Severe depression, anxiety, or other disorders affecting concentration and judgment.
- Substance or alcohol abuse – If you have a history of drug or alcohol misuse, this can lead to disqualification.

What Happens If You Fail the HGV Medical Exam?
Failing an HGV medical exam does not mean the end of your driving career. Here’s what you can do next:
1. Understand the Reason for Failure
Your doctor will explain why you did not pass. Some issues may be temporary and can be addressed with treatment or lifestyle changes.
2. Seek Medical Treatment and Reapply
If your condition, such as high blood pressure or poor eyesight, can be treated, follow your doctor’s recommendations. Once your condition improves, you can retake the medical exam.
3. Appeal the Decision
If you believe you were wrongly disqualified, you can appeal the decision. This may involve additional medical assessments or specialist reports to prove your driving fitness.
4. Apply for a Different Licence
If you are permanently unfit to drive an HGV, you may still qualify for a lower-category driving licence that does not have strict medical requirements.
5. Consult the DVLA
The DVLA provides guidance on specific conditions and whether they disqualify you from holding an HGV licence. If in doubt, consult them for clarification.

Can You Retake an HGV Medical Exam?
Yes, you can retake the exam once your health condition improves. Ensure you provide medical evidence if necessary. Many drivers pass their medical on a second attempt after making necessary adjustments.
Preventing Failure in Your HGV Medical Exam
To avoid failing your HGV medical exam, take these precautions:
- Maintain good vision – Regular eye tests and proper eyewear can help.
- Manage your blood pressure – Adopt a healthy lifestyle with a balanced diet and regular exercise.
- Control diabetes – Keep blood sugar levels stable with medication and diet.
- Address mental health concerns – Seek professional support if needed.
- Avoid alcohol and drug misuse – Follow DVLA guidelines for safe driving.
