(1) The general use of work zone speed control systems; or
(2) The segments of highways where and the dates and times when, work zone speed control systems may be deployed.
B. A minimum of two sets of signs approved by the State Highway Administration's Director of Traffic and Safety, alerting drivers to the possible operation of a work zone speed control system within the work zone, each set comprised of two signs, one on each side of the roadway, shall be conspicuously placed in advance of each work zone speed control system. The positioning and spacing of these signs shall be as approved by the agency that maintains the highway on which the work zone is located.
C. A device clearly displaying the speeds of vehicles approaching the device shall be placed sufficiently in advance of each work zone speed control system to enable an alert driver traveling at a speed not more than 25 miles per hour in excess of the speed limit to safely reduce the vehicle's speed to the legal limit prior to the location where the vehicle's speed will be measured by the work zone speed control system. The positioning of the device displaying the speeds of approaching vehicles shall be as approved by the agency that maintains the highway on which the work zone is located.
