If you need any more evidence that Cinco de Mayo is an American beer holiday rather than a Mexican celebration of an underdog victory over the French in 1862, look at the police crackdown on DUI suspects that''s taking place tonight and throughout the weekend.

If you don't act right, cops will be shooting fish in a barrel. So have that fishbowl margarita if you must, just don't drive afterward. Multiple SoCal police agencies have announced they'll be on high alert throughout the quasi-holiday weekend.

“Deputies from the Los Angeles County Sheriff’s Department’s DUI Enforcement Team will be deploying this weekend to stop and arrest alcohol- and drug-impaired drivers,” according to a sheriff's statement. “DUI saturation patrols will deploy on Friday, May 5, 2017, between the hours of 6 p.m. and 2 a.m. in areas with high frequencies of DUI collisions and/or arrests.”

Here are details on some of the anti-drunk-driving enforcement operations in Greater L.A., according to law enforcement:

Tonight from 8 p.m. to 1 a.m., a Los Angeles Police Department DUI checkpoint will be waiting for you at Manchester Avenue and Main Street in South L.A.
