The Kennewick Police are running ‘stings’ near Kamiakin where they pull over many drivers at once with an officer on foot. Speed limit signs are not very common, and you are reminded when caught that it’s 25 in residential areas unless otherwise posted. It’s basically a speed ambush; if they wanted you to slow down, they would put up more signs, as the streets are lightly traveled and 25 is low relative to similar Kennewick side streets.
