HGV licence is a key part of being a professional driver. Driving an HGV requires sustained concentration, physical stamina, and good overall health. Because of the responsibility involved, the DVLA has strict medical standards for Group 2 (HGV, LGV, and PCV) licences. At SimplyMedicals, we regularly see drivers who are worried about whether their health issues will impact their licence. Here are the most common conditions that can affect HGV eligibility — and what you can do about them.
Heart and Circulatory Conditions In HGV Licence
Cardiovascular disease is one of the most frequent medical concerns for HGV drivers.
1. High Blood Pressure
One of the most common reasons drivers need follow-up. If blood pressure is too high, the DVLA may temporarily refuse a licence until it’s controlled. Medication usually solves the issue.
2. Heart Attacks and Angina
After a heart attack, drivers must meet strict recovery criteria — including normal tests and clearance from a cardiologist. Many can return to driving once stabilised.
3. Arrhythmias
Irregular heart rhythms may cause dizziness or blackouts. If effectively treated (e.g., with medication or ablation), most people can still drive professionally.
Diabetes and Endocrine Conditions
Diabetes is increasingly common, especially among drivers who spend long hours sitting.
1. Type 2 Diabetes
Drivers using tablets or diet-controlled diabetes often have no restrictions. Regular monitoring is required.
2. Insulin-Treated Diabetes
Allowed — but only if blood sugars are well managed and the driver shows regular monitoring. Severe hypoglycaemia episodes can lead to licence suspension.
3. Obesity
Not a reason for refusal alone, but increases the risk of hypertension, sleep apnoea, and diabetes — all of which can affect fitness to drive.
Neurological and Sleep-Related Conditions
1. Sleep Apnoea
A major issue for commercial drivers. Untreated sleep apnoea leads to daytime sleepiness and increased crash risk. The good news: drivers can return once effectively treated (usually CPAP).
2. Epilepsy
Strict DVLA rules apply. Group 2 licences require long-term seizure-free periods without medication in most cases.
3. Stroke or TIA
A temporary driving restriction applies, followed by reassessment. Many return to work once stable.
Mental Health, Eyesight, and Other Conditions
Vision must meet DVLA Group 2 standards, and conditions like depression or anxiety are only relevant if they impair concentration or safety.
The key message: having a health condition doesn’t mean losing your HGV licence. What matters is stability, treatment, and compliance with DVLA rules. At SimplyMedicals, we guide drivers through the process and help with the medical evidence needed.
Ultimately, It all starts with your HGV medical Examinations.
