As a Jacksonville Traffic Lawyer, I am no stranger to speeding tickets. Jacksonville is full of speed traps. A Jacksonville Traffic Citation is issued pursuant to Section 316.87, Florida Statutes. This Florida Traffic Law permits the Florida Department of Transportation determine speed limits. Depending on the type of roadway or highway, the speed limit may not be greater than 60, 65, or 70 miles per hour (mph). Section 316.87(3) gives the authority to issue traffic citations based on speeding violations in Jacksonville, Florida. Section 316.1906, Florida Statutes, sets forth the rules for radar speed-measuring devices and the admissibly of evidence regarding these devices. Read 316.1906(2) for a list of criteria that this Florida Traffic Law requires.
