Apple updated its app developer guidelines Wednesday to exclude such apps. On Thursday, some DUI apps were still available in the App Store, but Apple usually gives developers a chance to update their apps so they can conform to the new guidelines before booting them.
The apps often combine warnings about DUI checkpoints, speed traps and red-light cameras. Users can register those locations.
An Apple spokesman had no comment on the change, and wouldn't say why it was made. Sens. Harry Reid, D-Nev., Charles E. Schumer, D-N.Y., Frank R. Lautenberg D-N.J., and Tom Udall, D-N.M., asked companies to remove DUI-avoidance apps. RIM complied, but Google refused.
