Equip all vehicles and equipment used in performance of the work with amber flashing lights. Equip tractors with two fender mounted amber flashing lights, two red flags mounted on each side of the rollover protective structure (ROPS) cage, a plainly visible rear mounted slow moving vehicle emblem, and working headlights. Keep all mowers in good operating condition and maintain to provide a clean sharp cut at all times. All equipment will be inspected by the engineer for safety devices and suitability for the work prior to being placed in operation. Properly maintain all safety devices and keep functioning at all times.
721.03 General Construction Requirements.
