Rule The traffic controller's instructions take priority over traffic lights and road signs. Explanation Watch the traffic controller carefully. If they face you with the baton pointed at you — you may only turn right. If they stand sideways with arms extended or lowered — you may go straight or turn right. If you see their back — you must stop. The blue car driver violates the rule because proceeding in the arrow direction is not permitted for them at this signal. Tip Slow down as you approach the intersection, get into the correct lane in advance, keep the traffic controller in your line of sight, and follow their signals immediately.
