Abstract
A review of the literature indicates that neither experimental nor epidemiological studies can give a clear indication as to whether orally administered diazepam adversely affects the ability of a patient to drive a car. It is preferable for anxious, aggressive, or depressed patients not to drive. Since diazepam tends to relieve these symptoms, this particular medication should not lead to an automatic prohibition of car driving. Patients should always be urged to use great care while at the wheel of a motor car.
