Sleep Drivers

Driving while sleepy can have devastating consequences, but it is an under-recognised problem often associated with behavioural factors, medical conditions or medications. All drivers have a responsibility not to drive if sleepy and there are DVLA regulations restricting driving for patients with certain sleep disorders who are at risk of excessive sleepiness at the wheel. However, sleepiness can be difficult for patient and doctor to assess and guidelines open to interpretation. As doctors it is important we give consistent and reliable advice to patients who may be at risk when driving. This review suggests how to assess driving risk, educate patients about risk reduction, and clarifies DVLA guidelines in this area.
