The report presents suggested criteria, warrants, and traffic control devices to design safe passing operations and designate no-passing zones on rural two-lane highways. The criteria are based on vehicle performance during the passing maneuver, the premise that sight distance should be provided at the critical postion when the passing and passed vehicle are abreast, and evaluation of traffic control devices in providing the required visual information at this critical position. An advance pavement marking system consisting of a short dotted yellow line adjacent to the roadway centerline throughout the pass completion distance is proposed, in conjunction with the no-passing zone pennant sign, to advise the passing driver that passing should not be initiated beyond the start of this marking system because there is not sufficient distance to complete the maneuver before reaching the no-passing zone. Warrants for no-passing zones are presented with lengths of advance treatment and minimum distances between successive no-passing zones for a range of expected operating speeds. An economic analysis of the expected benefits to be derived if the system were to be implemented nationwide indicates a high probability of being cost-effective.
