The San Diego Chargers are one of three NFL football teams to join a Mothers Against Drunk Driving designated driver program, MADD announced on Thursday.

MADD will have a presence in the Qualcomm Stadium parking lot on game days. Information cards will be distributed inside the facility, and an audio public service announcement will be played to encourage the use of designated drivers who remain sober to ensure everyone in their group returns home safely.

A one-day pilot program last year with the Buffalo Bills and Oakland Raiders proved successful, so the Chicago Bears and Philadelphia Eagles joined in as the season progressed, according to MADD.

"The NFL's partnership with MADD has proven to be valuable in raising awareness with fans, players and league employees of the need to make smart choices to ensure everyone's safety," said NFL Chief Security Officer Jeff Miller.

The Arizona Cardinals and Denver Broncos also joined the program this year with the Chargers.

The NFL plans to launch a Facebook campaign that discourages youth from underage drinking, and from getting into cars with people who have consumed too much alcohol.
