A traffic signal is a regulatory sign that changes its mind, and it outranks every sign and every marking at the intersection it controls. A green arrow beats the painted lane line; a traffic officer beats the signal.
The distinction the test cares about is steady against flashing. A steady red means stop and wait. A flashing red means stop, then go when the way is clear, exactly as if there were a stop sign there. A steady yellow means stop unless you are already too close to do so safely, and a flashing yellow means proceed with caution.
The filter arrows are the other favourite. An arrow only ever gives permission for the direction it points, and only while it is lit; when it goes out you are back under whatever the main disc is showing.
In the test: When the signals are dead, the intersection becomes a four-way stop. When an officer is directing traffic, the officer overrules the signal even when it is green.
