(A)   "Yield right-of-way": In addition to those state law provisions governing yielding right-of-way, no vehicle facing a "Yield Right-of-Way" sign shall enter the merging or intersecting right-of-way at a speed in excess of 15 miles per hour, except that this speed limit shall not apply to vehicles entering an expressway.
   (B)   Lane lights: When lane lights are installed over any street for the purpose of controlling the direction of flow of traffic, vehicular traffic shall move only in traffic lanes over which green arrows appear. However, when flashing amber lights appear above a lane all left turns shall be made from that lane. Where red arrows appear above such lanes, vehicles shall not move against them. If flashing amber lights show above a lane, that lane shall be used only for passing and for left turns unless a sign at such place prohibits such turn.
