Sleep apnoea is a common but serious sleep disorder that affects many people across the UK. Its impact extends beyond health—it can influence your ability to drive safely. The Driver and Vehicle Licensing Agency (DVLA) addresses sleep apnoea in Section 4 of the D4 medical form for drivers, particularly for those holding bus, coach, and lorry licences.
Here’s what you need to know about sleep apnoea and how it could affect your driving eligibility.
What is Sleep Apnoea?
Sleep apnoea causes interrupted breathing during sleep. The most common type, Obstructive Sleep Apnoea (OSA), occurs when throat muscles relax excessively, blocking the airway. Symptoms include:
- Loud snoring
- Gasping or choking during sleep
- Excessive daytime sleepiness
- Difficulty concentrating
- Morning headaches
- Episodes of stopping breathing
These symptoms can severely impair reaction times, alertness, and decision-making, all critical for safe driving.
Sleep Apnoea and the Law
If you have sleep apnoea, the DVLA needs to know if your condition affects your ability to drive safely. This applies to all drivers, but particularly to those holding vocational licences (e.g., HGV, PCV). You must report the condition if:
- You experience daytime sleepiness severe enough to impair your driving.
- You have been diagnosed with Obstructive Sleep Apnoea Syndrome (OSAS), where sleep apnoea leads to excessive daytime sleepiness.
If you’re unsure whether to notify the DVLA, consult your GP or a sleep specialist. Non-disclosure can result in fines and invalidation of your insurance.
What Happens When You Report Sleep Apnoea?
When you inform the DVLA, they will assess your case based on your diagnosis, treatment, and the impact on your driving. Factors they consider include:
- Diagnosis: Is it sleep apnoea or OSAS?
- Treatment Compliance: Are you managing your condition (e.g. Using CPAP therapy)?
- Symptom Control: Has treatment reduced excessive daytime sleepiness?
If the condition is well-managed and does not impair your ability to drive, your licence will likely remain valid. However, failure to follow treatment could result in suspension or revocation.
Can You Drive with Sleep Apnoea?
Most people with sleep apnoea can continue driving once their symptoms are controlled. To keep your licence:
- Follow Treatment Plans: Continuous Positive Airway Pressure (CPAP) machines are a common and effective therapy for OSAS.
- Attend Regular Check-Ups: Work with your GP or sleep specialist to monitor your progress.
- Be Honest About Symptoms: If daytime sleepiness persists despite treatment, avoid driving and inform the DVLA.
For vocational drivers, stricter standards apply. You must demonstrate that your condition is controlled effectively and that you are not at risk of excessive sleepiness.
Why Reporting Matters
Uncontrolled sleep apnoea significantly increases the risk of accidents, especially on long or monotonous routes common in lorry driving. Recognising and managing the condition benefits everyone on the road. Additionally, being proactive with the DVLA ensures you comply with the law and retain your licence when it’s safe to do so.
Where to Get Help
If you suspect you have sleep apnoea, consult your GP. Diagnosis often involves a sleep study, where your breathing patterns are monitored overnight. Once diagnosed, treatment can start, usually involving CPAP therapy or lifestyle changes.

Final Thoughts
Sleep apnoea doesn’t have to mean the end of your driving career. With proper diagnosis and treatment, many drivers lead safe and unrestricted lives. Whether you’re a private motorist or a vocational driver, managing your condition is key to staying safe on the road and compliant with the DVLA regulations.
