Speed Survey, Traffic Survey, or Engineer Survey
I was stopped for doing a 55 in a 35 zone. I have been doing a lot of research and have looked over some case law that suggest that there should be a speed survey available that would permit a legal speed enforcement (where an officer can set up radar). I understand that some of this information is covered in the MUTCD (manual of uniformed traffic control devises). I have contacted the DOT, which seems to be having a problem placing their hands on this material. How should I go about finding it or proving to the judge that this does not exist? Thanks.
