This commercial will give you the answer.
The advert features a man who is lying in a hospital bed in a serious condition from a road accident. This has happened apparently drunken driving. One of his legs has been removed. Now, we can hear his friend advising him against driving home because they have had a drink. As the words flow, the man in the hospital bed comes back to the normal stage- and he says to his friend – Yes, you’re right, I’ll sleep here.
The advert advices- Just a few words can be enough to save a life. Don’t let a friend who had a drink drive home.
