Is it illegal to talk on the phone while driving in Arizona?

Yes. Arizona law prohibits cell phone use while operating a motor vehicle that is not hands-free. Hands-free devices include ear pieces, headsets, or speakerphones. The law applies to all drivers, including those who are at least 18 years old and those under 18. Additionally, all devices must be used in a manner that does not interfere with the driver's ability to see clearly or to safely operate the vehicle.
