Radar; authorize sheriff and deputies to use on county roads to enforce speed limits.

HB 640 would amend Mississippi law to allow county sheriffs and deputies to use radar speed detection equipment on public roads, streets, and highways within their county that lie outside city limits. Currently, this use is restricted to specific municipal officers or the Highway Safety Patrol; the bill explicitly adds sheriffs as authorized users on all non-city county roads. This change directly affects drivers on rural county roads by expanding where speed enforcement via radar can occur. The bill died in committee in February 2025 and never became law.
