Beginning June 1, 2018, drivers in Rhode Island are forbidden to use ANY handheld device while driving. This currently includes handheld radios and even microphones typically used by RI hams. It is a $100 fine for violating this new law, although first time offenders who can prove they have ordered a hands-free device after their offense but prior to paying the fine, may have the fine suspended.
Many states exempt the use of hand-held microphones by hams, but this exemption did not make it into the RI law.
