This depends on whether you are suffering from symptoms that would impact on your driving. If you have sleep apnoea without any daytime sleepiness, you can keep driving and don’t have to tell the DVLA. But if you have sleep apnoea syndrome and symptoms severe enough to impact your driving, you must stop driving and tell the DVLA. Failing to inform the DVLA is a criminal offence, and it could affect your insurance cover. You can be fined up to £1,000 if you don’t tell the DVLA about a condition that affects your driving. If you’re not sure whether you need to tell the DVLA about your sleep apnoea, speak to your Doctor. There is also a really helpful leaflet produced by the DVLA that can help to make things more clear. It’s always better to be safe and double check if you are unsure, as the consequences of not reporting medical conditions can be severe.
