New speed cameras posted at 17 locations throughout Phoenix went live Monday.
Drivers caught violating the speed limit will receive a written warning by mail through March 24. Actual citations will be issued thereafter.
The city chose nine locations based on data involving the prominence of high-speed crashes.
The other eight are being posted in school zones that will rotate weekly throughout the year.
