maggiori limiti e sanzioni più severe dal 1 gennaio 2017 (fonte)

…While driving you can single swipe or tap the screen while it is in the mount in order to activate or deactivate a feature or function.
This is not meant to allow multiple taps or swipes such as texting or scrolling.

…After fees and penalty assessments are added the stated base fine, the ticket  will actually cost at least $160 for the first offense and at least $285 for the second offense.
