Three steady lights, two flashing lights, one arrow, and one dark intersection. That is the entire system. Learn what each one asks of you and no signal will ever surprise you again, on the test or on the road.
Everyone knows red, yellow, green. The test checks whether you know them exactly. Two of the three have a detail most drivers get wrong.
Come to a full stop and wait. Not a slow roll, not a look-both-ways-and-go. A complete stop, held until the light turns green. Where right-turn-on-red is allowed, you must still stop fully first and yield before turning.
Red = a wall of lightThe light is about to turn red. Slow down and stop if you can do so safely. Yellow is never an invitation to speed up and beat the light. That instinct is exactly what this test question is written to catch.
Yellow = the door is closingYou may go, if the way is clear. Green does not promise the intersection is empty. Check for cars still clearing, and for pedestrians, before you move. Green is permission, not protection.
Green = an open gate you still checkA protected turn. The arrow means oncoming traffic is stopped by a red light, so you may complete the turn safely. That word protected is the difference between the arrow and a plain green light, and the test loves that difference.
Arrow = your own private greenA flashing light is a signal wearing a different costume. Translate it back and the rule is one you already know.
A stop sign made of light. Come to a full stop, then go when it is safe. Same rule, same order of turns as a stop sign. Common at night, at broken signals, and at quiet crossings.
Blinking red = STOP signSlow down and proceed with caution. You do not need to stop, but you do need to arrive ready to. Flashing yellow hangs over intersections that are open but risky, so it asks for your attention, not your brakes.
Blinking yellow = eyes open, foot readyA power failure turns the busiest intersection in town into a test question. The rule is simpler than it feels in the moment.
When every light at an intersection is dark, treat it as an all-way stop. Every driver stops fully, then everyone takes turns, first to arrive, first to go. The dead signal does not mean the intersection is a free-for-all; it means everyone just got a stop sign.
A green light with a red left-turn arrow at the same time means: go straight if you wish, but left turns are still not allowed. Each part of the signal speaks to one movement. Read the arrow for your turn, the ball for going straight, and never mix the two.
The single most common signal mistake: treating yellow as speed up before it turns. The law reads it the other way: slow down, stop if you safely can. If you are too close to stop safely, continue through calmly. Racing a yellow is how intersections collect crashes.

1.A steady yellow traffic light warns you that:
A steady yellow light means the signal is about to change to red. Slow down and stop if you can do so safely.
2.A flashing red traffic light means:
A flashing red light works the same as a stop sign. You must stop fully, then proceed when it is safe.
3.A flashing yellow traffic light means:
A flashing yellow light means slow down and drive carefully through the intersection. You do not need to stop, but stay alert.
4.A green arrow signal pointing left means:
A green arrow gives you a protected turn. It means oncoming traffic has a red light, so you may complete the turn safely.
