Tucson's hands-free ordinance will get more strict February 1.
The city council voted last week to make using a phone while driving a primary offense. That means police can pull drivers over for violating the rule even if they are not breaking any other laws.
Tickets will cost drivers $143 for the first offense, $234 for the second offense, $417 for the third offense, and more than $500 if it is related to a crash.
Tucson will give drivers a grace period of one month to get used to the change. Fines start on March 3.
