What Do Flashing Traffic Lights Mean in British Columbia?

Quick Answer: A flashing traffic signal means the normal traffic light cycle is not operating. In British Columbia, a flashing red light requires you to stop before proceeding when safe, a flashing yellow light means proceed with caution, and a flashing green light identifies a pedestrian-controlled intersection where drivers must be prepared to stop for pedestrians.

Although flashing traffic signals are less common than normal traffic lights, every driver should understand what they mean. Knowing the difference between flashing red, yellow and green signals helps you make safe decisions when normal traffic control has been interrupted or modified.

What Does a Flashing Traffic Signal Mean?

Flashing traffic signals tell drivers that the intersection is operating differently than usual. Instead of following the normal sequence of green, amber and red lights, each flashing signal has a specific meaning that requires drivers to adjust their behaviour.

Each flashing colour has a different meaning, so always identify the signal before deciding whether to stop or proceed.

Flashing Red Traffic Light

A flashing red traffic signal has the same meaning as a stop sign.

• Come to a complete stop at the marked stop line or before entering the intersection.
• Yield to pedestrians and any traffic that has the right-of-way.
• Proceed only when it is safe to do so.

Do not assume cross traffic will stop unless it is also controlled by a flashing red signal.

If you encounter an intersection where the traffic lights are completely dark instead of flashing, read our article on traffic lights that are not working.

Flashing Yellow Traffic Light

A flashing yellow signal warns drivers to proceed with caution.

• Slow down as necessary.
• Watch carefully for pedestrians, cyclists and other traffic.
• Be prepared to stop if conditions require it.

You are not required to stop simply because the light is flashing yellow, but you must be prepared for unexpected hazards.

Flashing Green Traffic Light (British Columbia)

British Columbia is different from many other provinces.

In British Columbia, a flashing green light identifies a pedestrian-controlled traffic signal. Unlike in some other provinces, it does not indicate an advanced green turn signal. Drivers should be prepared for the signal to change when a pedestrian requests to cross. Wondering how the signal knows someone is waiting? Learn more about how traffic signals are triggered.

Drivers may continue through the intersection if it is safe, but they must remain alert because the signal can change to amber and then red after a pedestrian pushes the crossing button. Pedestrians using these crossings follow their own signal sequence. See our explanation of pedestrian signals to understand what they are seeing.

Do not mistake a flashing green light in BC for an advanced green turn signal. In some other provinces, flashing green has a different meaning.

Flashing Green Arrow

A flashing green arrow allows drivers to proceed only in the direction indicated by the arrow. Drivers must still yield to pedestrians lawfully crossing the roadway and to any conflicting traffic as required. Even a green indication doesn't always give you unrestricted right-of-way. Our article A Green Light Doesn't Always Mean Go explains why.

Why This Matters

Flashing signals are used because traffic conditions are not routine. They may appear during equipment failures, overnight operation, construction, emergency situations or at pedestrian-controlled crossings. The flashing light is intended to get your attention and remind you that the normal expectations at the intersection no longer apply.

Two common mistakes are treating a flashing yellow light like a normal green light and assuming that a flashing green gives you priority. Neither assumption is safe. A flashing signal is there because conditions aren't routine. Slow down, look carefully and don't assume other drivers are interpreting the situation correctly.

Most crashes at flashing signals aren't caused because drivers misunderstand the signal. They're caused because drivers assume everyone else is interpreting it the same way they are. A cautious approach gives you time to recognize when another driver has made the wrong assumption.

Flashing Lane Control Signals

Some roads use overhead flashing lane control signals.

• Steady Green Arrow: The lane is open to traffic.
• Steady Red X: Do not drive in the lane.
• Flashing Amber X or Arrow: Leave the lane safely because conditions ahead have changed.

British Columbia Law

The requirements described above are based on the Motor Vehicle Act and the guidance provided in Learn to Drive Smart. Drivers visiting British Columbia should be aware that the meaning of a flashing green signal is unique compared with some other Canadian jurisdictions.

These are some of the questions DriveSmartBC is most often asked about flashing traffic signals.
