Feel free to post whatever you know about traffic enforcement for law enforcement agencies in the upstate SC area. I thought we could have a new thread for 2010.
-Greenville County Sheriff... 12 deputies and 2 sergeants assigned to traffic unit, more radar usage than laser. laser very popular in school zones. they have about a half and half mix of unmarked and marked vehicles. the unmarked vehicles are mainly dark/navy blue crown vics. the marked vehicles are a mix of impalas and crown vics. all of the vehicles have front and rear radar (not sure if it is k or ka band)
Traffic unit is part of selective enforcement; they work all over the county, so it's not really easy to predict where you may encounter traffic officers. School zones are good bets, though. They are heavy on the Old Spartanburg Rd/Brushy Creek area during the weekday afternoons.
-Greenville City Police... fairly aggressive traffic unit, 5 if not more unmarked chargers (2 black, 2 dark titanium?, 1 white) all equipped with front/rear radar, no tint. I believe there are a couple of standard marked crown vics in traffic, as well as some marked/slicktop crown vic vehicles.
