Clarkson Valley, Missouri Speed Traps

Before you plan on turning on kehrs mill before rush hour track from 7am-10am, I recommend you not turn just because of inpatience to the light on Kehrs Mill, Cops love hiding into cars now and waiting for someone to just break the rule of illegal driving. You must wait to get into that lane when the lines divide that way, or you will get pulled more, trust me! Don’t let your impatience ruin your day please!

Speed limit is 30 miles an hour from Clarkson Road to Wild Horse Creek. It’s hard keeping within this limit as there are lots of hills where you pick up speed naturally without braking. Squad cars hide in the entrances of subdivisions and side streets making it very hard to view until it’s too late. There’s very low tolerance for speeders.
