SummaryWith an ageing population and more drivers on the road, the number of drivers with dementia is due to grow exponentially over the next 50 years. Although decisions regarding possession of a driving licence in the UK are made by the Driver and Vehicle Licensing Agency (DVLA), psychiatrists have a duty to advise patients who are unfit to drive to cease driving and to inform the DVLA of patients who pose a risk to the public by continuing to drive when advised not to. This article offers a review of the literature on dementia and driving and summarises the evidence and advice for navigating this minefield. The use of psychological test batteries in clinical practice is discussed, along with the most useful questions to ask in memory clinics. Legal guidance for various countries is considered, as is the important (but often overlooked) issue of helping older people prepare for retirement from driving.
