Driving under the influence. Most commonly alcohol. Something you shouldn't do but do it anyway until you get caught and goodbye license.

Driving Under the Influence. This is a couple BAC points down from DWI (Driving While Intoxicated). While you probably shouldn't do this,what many people don't remember is the old saying, "Beer before liquor, never been sicker; liquor before beer, and you're clear to steer."
Bob: I hear you got busted by the cops again last night.
Al: Yeah, it wasn't that bad, though.
Bob: What, DUI? THAT'S BAD, Al!!

Driving Under the Influence, pronounced dewey, refers to a person being arrested for driving after consuming alcohol. Generally people with DUIs are not drunk but just over the arbitrary limit of .08 and unlucky enough to get pulled over by a cop. If you get a DUI expect to pay a ton of fines, have your constitutional rights violated, and be treated like a criminal.

DUIs are great ways for cops to meet there quotas and politicians love them too because they bring in a ton of revenue for the state. These laws do little to actually make the public safer.
-hey bob, how was your weekend?

-It sucked, I got a dui. the fuckin pigs pulled me over for a broken tail light. I blew a .10 because I had four beers and now they're taking away my license for 7 months and fining me $5,000. Next time, I going to drink 20 beers because my lawyer says the penalties are the same if I do, I think I should at least get my money's worth.
