PIMA COUNTY, Ariz. - Pima County is cracking down on distracted drivers -- and it all starts Thursday.

A person may not use any handheld electronic device while driving unless it’s specifically designed to allow hands-free use. That means it’s not only illegal to text, but to make calls, check email, browse the internet or use your phone in general while you’re on the road in Pima County.

There was be a 60-day grace period to enforce the rule. During that time, drivers were given a written warning if they violated the ordinance, according to the Pima County Sheriff’s Office.

In April, Gov. Doug Ducey signed a law banning teens from texting and other cellphone use while they have a learner’s permit and during the first six months they have a regular license.

Though various cities in Arizona ban texting and driving, the state is one of only four without a blanket ban.
