Trapster and other apps that provide DUI checkpoint locations to users drew national attention when several U.S. senators, including Senate Majority Leader Harry Reid, called for Apple, Google, and RIM to ban them from their respective app stores. The senators took issue with the apps for identifying where local police set up drunk driving checkpoints, red light cameras, and speed traps, and argued that the apps promoted drunk driving by giving users a way to circumvent the checkpoints.
RIM eventually caved to the legislators’ demands. Apple kept the apps in its App Store, but set up new guidelines prohibiting developers from submitting new DUI checkpoint apps. Google still allows several such apps in its Android Market.
