What should you do when you approach a steady circular red traffic signal?

Answer: D — Stop, yield to traffic and pedestrians and proceed when safe

As a driver, it is important to follow traffic signals to ensure the safety of yourself and others on the road. When approaching a steady circular red traffic signal, it is important to come to a complete stop and yield to any oncoming traffic or pedestrians before proceeding when it is safe to do so. Option A is incorrect because it does not mention coming to a complete stop, while option B is also incorrect because you must yield before proceeding. Option C is incorrect because it does not mention yielding to traffic or pedestrians. Thus, option D is the correct answer as it includes all the necessary steps for approaching a red traffic signal.
