Learning Center · Lesson 2 · Traffic signals

Every light at every intersection, explained once.

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.

The three steady lights

Everyone knows red, yellow, green. The test checks whether you know them exactly. Two of the three have a detail most drivers get wrong.

Steady red

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 light

Steady yellow

The 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 closing

Steady green

You 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 check

Green arrow

A 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 green

The flashing lights

A flashing light is a signal wearing a different costume. Translate it back and the rule is one you already know.

Flashing red

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 sign

Flashing yellow

Slow 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 ready

The intersection with no lights at all

A power failure turns the busiest intersection in town into a test question. The rule is simpler than it feels in the moment.

Dark lights = all-way stop

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.

Green light + red arrow

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.

Yellow is not a challenge

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.
