It's up to you to make sure your guests get home safely. Here's how to plan in advance.


Let your guests know that no one drives away from your party under the influence of drugs or alcohol.

  • Include a time limit on your party invitation.
  • Ask guests to leave their keys at the door. Don't return the keys unless you feel it's safe to do so.
  • Plan ahead to designate a driver who will stay sober and drive drinking guests to and from home.
  • Look up a local taxi or ride share so you're prepared in advance to get your guests home safely.


Make a few tweaks to your guests' favourites.

  • High-protein foods stay in the stomach longer and slow the absorption of alcohol.
  • Carbonated mixers like pop speed the absorption of alcohol. Opt for a fizz-less mix instead.
  • Guests are less likely to over drink if they can keep track of the amount they've consumed. Keep a note pad near where drinks are being mixed and make sure to measure each drink - standard alcoholic beverages are 1 oz. of alcohol to a minimum of 6 oz. of mix.
  • Short-pouring a drink won't affect the taste, but will reduce the amount of alcohol your guests have at the party. Instead of 1 oz. of alcohol, pour a 1/2 oz. into a mixed drink instead.


If you have any doubt about whether a guest is impaired, don't let them drive. Help them find a safe ride home or offer them a place to stay instead.

Remember, as the host you may be held legally or civilly liable for damages caused by an impaired driver who drank too much at your party.
