When spending time in a club (pub):

1. It should be planned to wait one hour after leaving the pub, and then there should be no danger to drive.
2. It should be agreed that the person drinking the least amount of alcohol would drive after leaving the pub.
3. Correct answer: A designated driver, who abstains from drinking alcohol, should be determined in advance.
4. It should be agreed that the most experienced driver would drive after leaving the pub.

WhyDecide in advance who will drive, and that person does not drink at all. Neither experience, waiting an hour nor having drunk the least makes a drinker sober.
