1.

If it is a close friend, try and use a soft, calm approach at first. Suggest to them that they’ve had too much to drink and it would be better if someone else drove or if they took a cab.

2.

Be calm. Joke about it. Make light of it.

3.

Try to make it sound like you are doing them a favor.

4.

If it is somebody you don’t know well, speak to their friends and have them make an attempt to persuade them to hand over the keys. Usually they will listen.

5.

If it’s a good friend, spouse, or significant other, tell them that if they insist on driving, you are not going with them. Suggest that you will call someone else for a ride, take a cab, or walk.

6.

Locate their keys while they are preoccupied and take them away. Most likely, they will think they’ve lost them and will be forced to find another mode of transportation.

7.

If possible, avoid embarrassing the person or being confrontational, particularly when dealing with men. This makes them appear vulnerable to alcohol and its effects.
