The simple answer is "Yes, if you are tolerating treatment". All of us who have been diagnosed with OSA have been told of our legal responsibilities regarding OSA and driving. You MUST, by law, inform both the DVLA and your insurer that you have been diagnosed with apnoea. As a responsible Society we urge all our members who hold a licence to follow this advice. We realise that, quite naturally, when your living depends on driving you may be reluctant to inform the "authorities". There are several members who can, and will, attest to the fact that both the DVLA and insurers are quite happy to continue to allow you to drive and provide cover if you tolerate treatment. It is well worth knowing that the DVLA are aware of the fears of apnoea sufferers and have been involved in dialogue with Dr. Hack concerning this matter. They produce a booklet on the guidelines of fitness to drive. Visit the website: www.dvla.gov.uk
No matter what your fears please do the sensible thing and inform both the DVLA and your insurers. You know it makes sense.
