Yellow warns that the light is about to change; green lets you go only when the way is clear. Overhead lane signals tell you which lanes are open at different hours, and pedestrian hybrid beacons stop traffic for walkers at crossings with no regular stoplight.

Know the rule

Steady yellow light or arrow: if you haven't entered the intersection, stop; if stopping is unsafe, cautiously go through. If you're already in the intersection, go through cautiously. Never speed up to beat the light.

Handbook p. 7 ↗

Know the rule

Flashing yellow light: slow down and proceed with caution. These are used at locations with higher-than-normal hazards.

Handbook p. 7 ↗

Know the rule

Flashing yellow arrow: you may turn in the arrow's direction if clear, yielding to oncoming vehicles and pedestrians. If it changes from red while a pedestrian is crossing, let them finish first.

Know the rule

Green light: go if the way is clear. Green arrow: go in the arrow's direction if clear. Turning without a green arrow, yield to oncoming vehicles and pedestrians in the intersection.

Handbook p. 8 ↗

Know the rule

If a light turns from red to green while a pedestrian is in the street, let the pedestrian finish crossing before you turn.

Handbook p. 8 ↗

Know the rule

Signals out of service (dark, no lights): stop and proceed as though it were an all-way stop, unless an officer or authorized person is directing traffic or portable stop signs are in use.

Pedestrian Hybrid Beacon (PHB) sequence:

  • Used over intersections without stoplights when pedestrians are at a crosswalk
  • 1. A pedestrian activates it: the single bottom yellow light flashes
  • 2. The yellow turns solid: prepare to stop
  • 3. Both top red lights turn solid while the walk signal shows: you must stop
  • 4. Reds alternate flashing during the countdown: go with caution if the crosswalk is clear

Put it into practice

You're 50 feet from the intersection when the light turns yellow. Stop if you can do it safely. If you're already in the intersection, keep going cautiously. Don't accelerate to beat the red.

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.

What does a flashing yellow light mean?
  1. Stop completely before proceeding
  2. Proceed at normal speed; it is only advisory
  3. Yield only to pedestrians, not vehicles
  4. Slow down and proceed with caution

Answer: Slow down and proceed with caution

A flashing yellow light warns of a higher-than-normal hazard; slow down and proceed with caution.

Handbook p. 7 ↗
At a flashing yellow arrow, what must you do before turning?
  1. Yield to oncoming vehicles and pedestrians in the intersection
  2. Stop completely and wait for a green arrow
  3. Proceed immediately without yielding
  4. Yield only to pedestrians, not vehicles

Answer: Yield to oncoming vehicles and pedestrians in the intersection

At a flashing yellow arrow you may turn if the way is clear, but must yield to oncoming traffic and pedestrians.

Handbook p. 7 ↗
At a green light, when turning without a green arrow, who has the right-of-way?
  1. The turning driver always
  2. Oncoming vehicles and pedestrians in the intersection
  3. Whoever arrives first
  4. The driver on the right

Answer: Oncoming vehicles and pedestrians in the intersection

When turning on a green light without a green arrow, you must yield to oncoming vehicles and pedestrians in the intersection.

Handbook p. 8 ↗
Traffic signals at an intersection are completely out of service due to a power outage. How should you proceed?
  1. Proceed at normal speed since no signal applies
  2. Only vehicles on the main road may proceed
  3. Treat the intersection as an all-way stop
  4. Slow down and treat it as a yield

Answer: Treat the intersection as an all-way stop

When signals are out of service and dark, you must stop and proceed as though it were an all-way stop intersection.

Handbook p. 8 ↗
What should you do when you see a yellow X or a yellow diagonal downward arrow lane signal?
  1. Leave the lane as soon as it's safe
  2. Stop immediately in that lane
  3. Speed up to clear the lane
  4. Ignore it since it is only a warning

Answer: Leave the lane as soon as it's safe

A yellow X or yellow diagonal downward arrow means you should move out of that lane as soon as it's safe.

Handbook p. 8 ↗
When the red lights on a Pedestrian Hybrid Beacon begin to alternate flashing, what does that mean?
  1. Drivers must remain stopped until the lights go dark
  2. Drivers should prepare to stop
  3. Pedestrians may no longer cross
  4. Drivers may go carefully if the crosswalk is clear

Answer: Drivers may go carefully if the crosswalk is clear

While the alternating flashing red lights show, drivers may proceed with caution once the crosswalk is clear.
