Ottawa, Kansas Speed Traps
While west bound on 15th street, the speed limit is 40mph. The speed trap begins with a sign with the words "BEGIN 30 MILE SPEED" (in very small print). A large hill follows this sign, and at the bottom of the hill is the first REAL sign stating the limit to be 30mph.
Motorists will typically not see the first sign because it is a non-standard sign and the print is very small. The motorists speed at the bottom of the hill will usually be greater than 40 mph because they enter into the downhill at 40mph. The police will measure your speed at the bottom of the hill at the first REAL 30mph sign. A 2nd 30mph sign is posted about 70 yards after the first one, but you will still get a ticket even if you reduce your speed before passing the 2nd sign.
