Sleep driving,[1] also known as sleepwalk driving,[2] is a rare phenomenon where the person drives a motor vehicle while they are sleepwalking.
If stopped by police, sleepwalk-drivers are totally incapable of having any interaction with the police, if they are still sleepwalking during the event.
[3] Sleepwalk-driving can occur to people who normally don't experience sleepwalking, since some medications, especially zolpidem and eszopiclone, can cause sleepwalking as unwanted side effect.
[4] A case of a fatal hit-and-run accident involving the driver claiming to be sleep-driving has been recorded.
However, no evidence of the claims could be found by a sleep expert during the following trial.
