Sobriety checkpoints set up by Southern California law enforcement agencies are prevalent during the holidays. Studies show that more drivers take to the road under the influence of alcohol and other substances.
Authorities say the checkpoints, funded by the California OTS, Office of Traffic Safety, are carried out in order to keep people safe from drunken drivers. But activists claim the majority of those arrested don't pose a danger to other drivers. One of the sobriety checkpoints was conducted in La Puente this weekend.
