Governor Rick Scott of Florida signed 44 bills in to law on May 21st, one of which was SB 570, which allows service of subpoenas by United States mail on witnesses in civil traffic cases.
The law will become effective on July 1st, 2015.
The code already allowed service of subpoenas on witnesses of a criminal traffic case, a misdemeanor case, or a second or third degree felony. The subpoena must be mailed the witnesses last known address at least seven days prior to the date of the required appearance.
A witness who does not appear in response to a subpoena that was not sent by certified mail may not be held in contempt of court.
