1.2.2 Vasovagal syncope
The most common cause of transient loss of consciousness is vasovagal syncope (‘fainting’). Where this has been triggered by a well- defined provoking factor or a situation that is unlikely to recur while driving (e.g. prolonged standing, venepuncture or emotional situation), it is not necessary to restrict driving. However, vasovagal syncope may also result from other causes that are not so benign. In such cases, fitness to drive should be assessed according to the cardiovascular conditions standards for syncope (refer to section 2 Cardiovascular conditions).
