You are required to stop your vehicle:

  1. At any intersection where a police officer orders you to stop.
  2. Where there is a red traffic light.
  3. Both of the above. ✓

Answer: C. Both of the above.

You must stop in both situations: when a police officer orders you to stop at an intersection and when you face a red traffic light.

Why this is the answer

Both situations require you to stop. The handbook says a solid red traffic signal means stop. It also says you must obey any direction, order, or signal from a law enforcement officer, and follow those orders even when they conflict with existing signs, signals, or laws. So a police officer directing you to stop at an intersection is a stop requirement, and a red light is a stop requirement too. Choosing only one of these leaves out the other.

Why the other answers are wrong

Remember it

Picture a red light and an officer's order as two separate stop signs.
