What should I do instead of driving after drinking?

The answer

Plan your way home before the first drink, and never drive after drinking or ride with a driver who has been drinking. Choose a designated driver who will not drink alcohol at all, arrange a taxi or ride service, use public transit or stay overnight where you are, and collect your car the next day. You cannot reliably judge your own impairment, because alcohol affects judgment and reaction time, often before you feel it.
