Designated driver

The terms "designated driver" and "designated driving" refers to the selection of a person who remains sober as the responsible driver of a vehicle whilst others have been allowed to drink alcoholic beverages. Thus as a practical and ethical matter a designated driver is a person who abstains from alcohol on a social occasion in order to drive his or her companions home safely as an alternative to driving under the influence. In order to encourage these arrangements, some bar, restaurant and nightclub proprietors will offer free or reduced-price non-alcoholic drinks to designated drivers.
