On a daily basis, the OK State Troopers hide completely out of view, over the the crest of a hill, in low-lying grassy ditches behind the crash water barrels, totally out of sight, at the highway sign posts, within 100 ft (1 second at 70 mph) of passing view. There is NO CHANCE WHATSOEVER of seeing them, or slowing down before you are clocked, busted! A radar detector DOES pick them up very well in advance, but only IF they aren’t using instant-on radar (which Ive never encountered in this speed trap area). Heads up! Don’t speed west bound I-240 from Tinker to Sunnylane, unless you consider yourself the expert speeder. Oklahoma troopers will do anything to collect your money, so don’t speed if you don’t know the tricks.
