Signals keep traffic moving and prevent crashes at intersections. Drivers, pedestrians and bicyclists must all obey them unless an officer is directing traffic. A round light controls the whole intersection. An arrow controls only the movement it points to.

Steady red light:

  • Stop completely at the stop line and stay stopped until green
  • Don't stop too far back; some signals change only when sensors detect a vehicle at the line
  • After stopping, you may turn right if clear and no NO TURN ON RED sign is posted
  • You may turn left from a one-way street onto a one-way street with traffic moving left
  • Before turning, yield to pedestrians in the crosswalk and to oncoming traffic

Know the rule

Steady yellow: the light is changing to red. Stop if you can do so safely. Being in the intersection when it turns red is extremely dangerous.

Steady green light:

  • Go, but only if the intersection is clear
  • Yield to pedestrians in the crosswalk and vehicles already in the intersection
  • Approach at a speed that lets you slow down if the light changes
  • When turning left, yield to oncoming traffic and pedestrians

Arrow signals

Arrow signals
ArrowMeaning
Red arrowDon't make that movement until green appears
Yellow arrowGreen arrow ending or light about to turn red; stop if safe
Green arrowYou may turn that way; yield to vehicles/pedestrians in it
Flashing yellow arrowTurn allowed; oncoming has green, so yield to it
Handbook p. 60 ↗

Know the rule

At a red arrow, the same exceptions as a red light apply: after stopping, a right turn on red (or a left from one-way onto one-way) is allowed if clear and not prohibited, yielding to pedestrians and oncoming traffic.

Handbook p. 60 ↗

Know the rule

A green arrow showing with a red light means you may make the arrow's turn, as long as you're in the proper lane for it.

Know the rule

Running (driving through) a red light is against the law and extremely dangerous.

Put it into practice

You're waiting to turn left and the signal shows a flashing yellow arrow. You may turn, but oncoming traffic has a green light. Wait for a safe gap and yield to pedestrians before you go.

Check your understanding

Read the question, decide on an answer, then open it to check the explanation. These are Roadwise study questions based on the source handbook.

At a steady red light, after coming to a complete stop, when may you turn right?
  1. Only if a green arrow appears
  2. With no NO TURN ON RED sign, if clear
  3. Only if a police officer waves you through
  4. Never, right turns on red are always illegal

Answer: With no NO TURN ON RED sign, if clear

After stopping at a red light, you may turn right if there is not a NO TURN ON RED sign and the way is clear.

Handbook p. 59 ↗
From a one-way street, you can turn left on red onto another street if:
  1. Only if a sign permits left on red
  2. There is a green arrow present
  3. It is also one-way, flowing left
  4. The other street is two-way

Answer: It is also one-way, flowing left

You may turn left from a one-way street onto a one-way street that has traffic moving to the left.

Handbook p. 59 ↗
At a green light, before proceeding through an intersection you must:
  1. Check it is clear; yield to pedestrians
  2. Wait three seconds after it changes
  3. Immediately accelerate to clear it
  4. Only check for oncoming traffic if turning

Answer: Check it is clear; yield to pedestrians

At a green light, go only if the intersection is clear, and yield to pedestrians in the crosswalk and vehicles in the intersection.

Handbook p. 59 ↗
A red arrow signal means you:
  1. Should treat it exactly like a flashing red light
  2. Must wait for green to make that move
  3. Must reverse direction
  4. May proceed cautiously in the arrow's direction

Answer: Must wait for green to make that move

A red arrow means do not make the movement shown by the arrow until the green light appears.

Handbook p. 60 ↗
A green arrow displayed at the same time as a red light means you:
  1. Must wait for the red light to turn green first
  2. May go straight through the intersection
  3. May turn that way from the proper lane
  4. Should treat it as a flashing yellow

Answer: May turn that way from the proper lane

A green arrow lets you turn in that direction; if a red light shows at the same time, you must be in the proper lane for the turn.

Handbook p. 60 ↗
A flashing yellow arrow means:
  1. The signal is malfunctioning; treat as four-way stop
  2. You must stop completely
  3. No turns are allowed at all
  4. Turn allowed; yield to oncoming traffic

Answer: Turn allowed; yield to oncoming traffic

A flashing yellow arrow allows turns in that direction, but oncoming traffic has a green light, so you must yield.
