Explanation:

California law specifically prohibits texting while driving as it is a major distraction. Hands - free talking is generally allowed (with some exceptions for certain drivers like novice drivers). Using a phone for navigation is also not illegal as long as it is done in a safe manner. And it is not all cell phone usage that is illegal regardless of age.
