Traffic signals control intersections where movements conflict. Each color, arrow and flash has an exact legal meaning, including two turns you may make on red in Hawaii.

At a steady red light, stop:

  • At the stop line
  • If there's no stop line, before entering any crosswalk
  • If there's no stop line or crosswalk, before entering the intersection
  • And stay stopped until the signal turns green

Put it into practice

You're stopped on red on a one-way street, and the cross street is also one-way with traffic moving to your left. With no sign prohibiting it, you may turn left on red after a complete stop, yielding to pedestrians and traffic.

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.

A steady red traffic light means you must:
  1. stop, then go straight if no one is coming
  2. stop and stay stopped until it changes
  3. slow down, but you may still proceed
  4. yield only if pedestrians are present

Answer: stop and stay stopped until it changes

A red light requires a full stop until the light changes.

Handbook p. 39 ↗
After stopping at a red light, when may you turn right (absent a sign prohibiting it)?
  1. Only if an officer directs you to
  2. Only during daylight hours
  3. Never, under Hawaii law
  4. After yielding to pedestrians and vehicles

Answer: After yielding to pedestrians and vehicles

A right turn on red is allowed after yielding to pedestrians and vehicles, unless a sign prohibits it.

Handbook p. 39 ↗
On a one-way street, you may turn left on a red light into another one-way street where traffic moves to the left if:
  1. you are the first car at the light
  2. the cross street has two or more lanes
  3. no posted sign prohibits it
  4. it is never allowed in Hawaii

Answer: no posted sign prohibits it

A left turn on red from one one-way street to another is allowed unless a sign prohibits it.

Handbook p. 39 ↗
A steady yellow traffic light means:
  1. red is coming; avoid entering the intersection
  2. speed up to beat the red light
  3. pedestrians may start crossing
  4. you must stop at once, however close you are to it

Answer: red is coming; avoid entering the intersection

Yellow warns that red is coming; you should avoid entering the intersection.

Handbook p. 39 ↗
A red flashing traffic signal has the same meaning as a:
  1. Railroad crossing signal
  2. Do Not Enter sign
  3. Stop sign
  4. Yield sign

Answer: Stop sign

A flashing red signal is treated the same as a stop sign.

Handbook p. 41 ↗
A yellow flashing traffic signal means you:
  1. must come to a complete stop
  2. must stop and yield to all cross traffic
  3. may proceed, but only with caution
  4. must stop only if turning left

Answer: may proceed, but only with caution

A flashing yellow signal means proceed with caution.
