What is a microsleep?

Correct answer

A period of a few seconds during which the driver briefly falls asleep without realising it.

It is a brief, involuntary sleep episode lasting a few seconds that the driver may not notice. Attention and response are lost during it; it is not a controlled rest break. If sleepy, stop driving and stop in a permitted, safe place to rest. Do not rely on music or open windows to prevent it.
