For which of the following traffic lights must you always stop your vehicle?

You must stop at a solid or flashing red light, or at a signal light that is blacked out (not working). A solid yellow light means that the signal is about to turn red and you must stop if you can do so safely; otherwise, proceed cautiously. A flashing yellow light means that you should proceed with caution, but you do not need to stop.
