How much is the ticket for Goin 78 on a 45 speed limit IN FLORIDA?

Citations and fines are controlled by the local municipality that the violation occurred in, no matter whether the ticket was issued by State Patrol, Sheriff's Deputy, or City Police. If you were in the City, call the Magistrate Judge in that city. If in the County it will be Magistrate or Probate in the county listed on the citation. Try to get the speed reduced to less than where it is. Most insurance companies consider 20 mph over the speed limit as a major violation and you don't want that.
