In a move that's bound to get at least a few MADD moms smiling, Apple's officially decided to block apps that encourage drunk driving. Section 22.8 of the newly revised App Store Review Guidelines reads:

Apps which contain DUI checkpoints that are not published by law enforcement agencies, or encourage and enable drunk driving, will be rejected.

That revision comes on the heels of a request from Senate Majority Leader Harry Reid, asking that Google, Apple, and RIM yank offending apps from their respective mobile outlets. At the time, Google declined while RIM was quick to jump on the bandwagon, leaving Apple to stew. For now, it looks like the rest of us still have to keep our eyes out for Android users with a propensity for boozing and skirting the fuzz.
