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. (source:

*What service establishments should do to run a good Designated Driver Program.

  • Assign a staff member at all times
  • Check for age and fake IDs
  • Deny entry to intoxicated people
  • Count the number of patrons on the premises to prevent overcrowding
  • Provide a proper patron-staff ratio

Actively encourage food consumption

  • Offer reduced food prices during late afternoon/evening
  • Have low cost snacks or food available at all times
  • Provide incentives to servers for increased food sales

Promote alternative beverages

  • Price non-alcoholic drinks significantly less than those containing alcohol
  • Promote non-alcoholic drinks on table tents
  • Stock and promote light beer and light wine
  • Set lower prices for light beer and light wine
  • Evaluate servers on total sales, including non-alcoholic products

Train all staff

  • Involve all staff in server training, so they understand what a DDP is
  • Pay staff for training time
  • Keep an incident log of all problem situations

Provide house policies

  • Provide a written statement of policies to all staff
  • Prohibit drinking on the job by employees
  • Reinforce policies by offering staff incentives for effectively managing intoxicated patrons and for selling alternative beverages
