Rules for no-passing zones on county roads

(a) The County engineer and district engineer are authorized to determine those portions of any highway where overtaking and passing or driving to the left of the roadway would be especially hazardous and may by appropriate signs or markings on the roadway indicate such zones. When signs or markings are in place and visible to an ordinarily observant person, every driver of a vehicle shall obey the directions thereof. (b) A no-passing zone shall be designated by a sign placed at the edge of the roadway at the beginning and at the end of such zone or by a solid yellow line placed as the right-hand element of a combination line along the center line. (c) Where such signs or markings are in place to define a no-passing zone, no driver shall at any time drive on the left side of any pavement striping designed to mark such no-passing zone throughout its length except when making a left turn. (d) Determination for no-passing at curves and signs and markings designating no- parking zones shall be in accordance with the “Manual on Uniform Traffic Control Devices for Streets and Highways” (MUTCD) published by the U.S. Department of Transportation, Federal Highway Administration, 1978 edition, as revised from time to time. The MUTCD is on file and is available for public inspection at the County clerk's office. (e) Where the width of winding or hilly roads is less than eighteen feet, the County engineer and district engineer are authorized to use advisory and warning signs indicating the winding or hilly condition of the route and the narrowness of the road instead of standard signs and markings for no passing zones required under subsection (d) of this section. These warning and advisory signs shall be placed at the beginning of the winding or hilly road and at intervals of not more than two miles. Standard broken center line may be used on these narrow roads as a guide line for motorists, also when special conditions exist along these narrow winding roads a single solid yellow line may be installed at specific areas to designate a no passing zone (both directions of travel). The County engineer and district engineer shall designate those areas which warrant the use of a single solid yellow line.
