Apple bans DUI checkpoint apps

Apple will ban apps that warn drivers of DUI checkpoints, according to changes in the company's App Store Review Guidelines. The move comes four months after several U.S. senators called for the company to reject apps like Trapster and PhantomALERT that forewarn drivers of cops' roadblocks.

Four US senators, Chuck Schumer, Frank Lautenberg, Harry Reid and Tom Udall sent a letter to several companies, including Apple and Google, back in March saying checkpoint applications put "innocent families and children at risk." RIM has already removed DUI checkpoint apps from its "App World."

Millions of users have downloaded copies of such apps, but developers have denied that they're encouraging drunk driving; Trapster creator Pete Teneriello points to his app's "find a taxi" prompt as proof.

But is the genie out of the bottle? With such apps relying heavily on crowd sourcing for their information, it's possible the crowd will find their own way to thwart the rules by masking DUI checkpoints in code. Either way, the matter won't likely end here.
