On SR 874, south of Kendall Drive (SW 88 Street), near Killian Parkway, there are white solid lines accross the pavement used by Florida Highway Patrol planes to clock drivers. There is one line, then another, and yet another one, both north and southbound. The pilot clocks the drivers and the ground troopers stop them and write the tickets. The speed limit is 60 mph, but the prevailing safe speed of traffic is 75 – 80 mph. They ususally don’t bother those driving below 70 mph.
