Changes to EU legislation (European Commission directive 2014/85/EU) came into force in Great Britain on 31 December 2015 and affect the minimum medical standards for drivers with Obstructive Sleep Apnoea Syndrome (OSAS).
Drivers with OSAS must inform DVLA at the point of diagnosis or recognition of symptoms. This can be done by letter, phone or email and the driver must stop driving completely until their condition has been successfully treated. Treatment is widely effective but medical enquiries will be undertaken by DVLA. Drivers with Obstructive Sleep Apnoea (OSA) (not OSAS) do not need to notify DVLA unless they have symptoms (e.g. daytime sleepiness) that would affect their ability to drive safely.
Cars and motorcycles (Group 1 entitlement) – driving must stop if there is OSAS and symptoms including excessive sleepiness severe enough to likely impair safe driving. Driving will be permitted once satisfactory control of the symptoms has been achieved.
Lorries and buses (Group 2 entitlement) – as above but drivers must also comply with the treatment specified and confirmed to the DVLA by the consultant/specialist.
