Can coffee replace rest and sufficient sleep for driving without drowsiness?

Correct answer

No; possible temporary help does not replace sleep and rest.

No. It may help temporarily in some situations, but does not remove the need for sleep or guarantee sustained attention. The DGT warns that drowsiness can return suddenly as its effects wear off. If sleepy, stop in a permitted, safe place and obtain the necessary sleep before continuing. Coffee does not justify driving while tired.
