The City of Grover Beach has reduced the speed limit on Oak Park Boulevard south of Highway 101 to 25 MPH. Signs warning of radar enforcement of that speed limit have been added. California’s “speed trap” law makes it a crime to use radar to enforce speed limits on such roads as Oak Park Boulevard when speed limits are below the 85th percentile of all speeds observed via
Grover Beach’s Special Traffic Study No.1, available at their website, states that a 2008 survey established the 85th percentile speed as 38 MPH on this section of Oak Park Blvd. (grover.org/pdf/SpecialTrafficStudiesNo1-OmniMeans-11-25-08.pdf).
Existing legal interpretation strongly suggests that any speeding ticket issued on this stretch of Oak Park, regardless of the method of enforcement and even regardless of the motorist’s speed, will be dismissed if challenged in court. If you win a speed-trap case you should thank the court for dismissing the case. You may then request that the court find the ticketing officer in contempt under section 1209(a) of the Code of Civil Procedure.
