How Smoking Affects Your Driver Medical
When it comes to passing your driver medical — whether it’s for an HGV, PCV, Taxi, or C1 Ambulance licence — your overall health matters. One of the biggest lifestyle factors that can negatively impact your results is smoking. While you might think a few cigarettes a day won’t make a difference, smoking can significantly affect key areas assessed during a driver medical. Here’s how.
What Is Checked During a Driver Medical?
At Motor Medicals, our GMC-registered doctors carry out comprehensive assessments to ensure you’re fit to drive professionally. These include:
Blood pressure check
Urine test (for diabetes or other conditions)
Vision and visual field tests
Cardiovascular and respiratory health
Medical history review
Smoking can negatively influence many of these areas — and that can put your licence application or renewal at risk.

The Impact of Smoking on Your Medical Results
1. Raises Your Blood Pressure
Nicotine causes blood vessels to constrict, leading to higher blood pressure. Consistently raised blood pressure can be a red flag during your medical and may require additional investigations or a follow-up from your GP.
2. Increases the Risk of Heart and Lung Disease
Driver medicals look for signs of cardiovascular or respiratory problems. Smoking damages both systems over time, increasing your risk of:
Shortness of breath
Chest pain
Irregular heartbeat
Reduced lung capacity
These symptoms could lead to medical conditions that disqualify or delay your licence approval.
3. Affects Your Vision
Smoking has been linked to an increased risk of cataracts and age-related macular degeneration — both of which can affect your ability to meet the DVLA’s eyesight standards.
4. Reduces Stamina and Alertness
Long driving shifts demand good stamina and alertness. Smoking reduces oxygen levels in your blood, which can lead to fatigue, slower reaction times, and reduced concentration behind the wheel.
Other Considerations for Smokers
Chronic Cough or COPD: If you have a chronic cough or symptoms of COPD, this may be noted during the medical and could lead to further questions or referral.
Medication Use: Smokers are more likely to be on medication for blood pressure or heart issues — these must be disclosed during your medical.
Chest X-rays or ECGs: In some cases, additional tests may be required based on symptoms linked to smoking.
Can smoking stop you from passing your medical?
Smoking doesn’t automatically disqualify you from passing a driver medical — but it can affect your results in ways that might delay or complicate your licence application. Being aware of these risks and preparing accordingly can help you pass your medical smoothly. If you’re unsure about how smoking might impact your results, speak to our team — we’re here to help.
