In an effort to fight drunken driving, Budweiser is teaming up with ride-sharing company Lyft to offer 150,000 free rides in nine states beginning today.

Budweiser will release special promo codes each weekend on its Facebook and Instagram pages, Fortune reported.

It's part of the "Give A Damn" campaign - 10,000 rides will be offered each weekend through Dec. 31. Promo codes will be released at 2 p.m. every Thursday, The Washington Post reported.

The first 10,000 new or established Lyft users will get two $20 ride credits. They’re valid for three days and can be used from 5 p.m. and 5 a.m. But the time is ticking on the credits. If not used by Sunday morning, they go away.

A pilot program was tested last year in New York, Colorado, Illinois and Florida, the Post reported.
