Hazard Marker Sign

Introduction

When driving through construction zones, tight corners, or road splits, visual cues are critical for guiding vehicles safely. The Hazard Marker sign, particularly this diagonal striped version, is used throughout Canada to indicate the edge of a physical obstruction. It helps drivers make safe maneuvers around barriers, curbs, or dividers.

What Does the Hazard Marker Sign Mean?

This black-and-yellow striped vertical sign is a directional hazard marker. The stripes are angled from the top left to bottom right, meaning the obstruction should be passed on the right side.

• Diagonal stripes: Indicate direction to pass

• Yellow and black coloring: Standard for hazard warnings

• Vertical orientation: Mounted on posts or guardrails

This version tells the driver:
🡪 Keep right of the hazard

Where Are Hazard Markers Typically Placed?

Expect to see this sign in places like:

• The end of guardrails or median barriers

• Sharp bends with narrow clearance

• Construction zones with new lane alignment

• Bridge approaches or tunnel entrances

• Around fixed objects like poles or overpasses

It’s also common in rural and highway settings where roads divide.

How Should Drivers Respond?

When you see this sign:

• Slow down and prepare to steer around the object

• Always pass on the side the diagonal lines point toward

• Avoid sudden lane shifts or overtaking near the hazard

• Be cautious in poor weather or nighttime, as visibility can reduce reaction time

Ignoring the sign can lead to collisions with fixed objects or barrier impacts.

Visual Representation of the Sign

• Rectangular shape with alternating yellow and black stripes

• Diagonal lines sloping from upper left to lower right

• Standard width and height to be visible from a distance

Conclusion

Hazard Marker signs like this one are not just cautionary—they give specific directional instructions to avoid crashes. For G1 test preparation or general road awareness, knowing what side to pass on is essential. Always observe the slope of the lines—they point away from the hazard and toward your safe path forward.
