The first set is RCW 46.61.405, 46.61.410, 46.61.415, and 46.61.419, which give various people the authority to set signed speed limits, obedience to which is required by RCW 46.61.050. The second is RCW 46.61.400(2), which establishes default speeds of 25 MPH on city streets, 50 MPH on county roads, and 60 MPH on state highways. This would seem rather comprehensive, except for: The third law: RCW 46.61.400(1). "No person shall drive a vehicle on a highway at a speed greater than is reasonable and prudent under the conditions and having regard to the actual and potential hazards then existing." As a highway engineer pointed out to me recently, most county roads, especially unpaved ones, are designed around a speed limit of "reasonable and prudent". The 50 MPH limit established by RCW 46.61.400(2)(b) simply sets a firm upper boundary; it's quite possible to get a speeding ticket at a lower speed. Sure, you can put a number on any road. But for most rural roads without speed-limit signs, the number is unrelated to how fast you can drive on that road. -- Mark _______________________________________________ Tagging mailing list Tagging@openstreetmap.org https://lists.openstreetmap.org/listinfo/tagging
