Checkerboard Sharp Turn Sign

Introduction

Certain road situations require immediate and clear visual cues to help prevent accidents—especially at sudden curves, dead ends, or T-intersections. The Checkerboard Sharp Turn Sign, often called the checkerboard pattern warning sign, is used across Canada to alert drivers of a very sharp change in direction. It’s a vital sign for new drivers preparing for their Ontario G1 driving test.

What Does the Checkerboard Sharp Turn Sign Mean?

This sign is a high-visibility warning sign that features:

• A black arrow on a yellow diamond background, indicating the direction of the upcoming sharp turn (left or right)

• A surrounding checkerboard pattern in alternating black and yellow squares

The sign signals that a sharp turn or road termination is directly ahead and that drivers must slow down and follow the arrow’s direction immediately.

Where Are Checkerboard Turn Signs Typically Placed?

This sign is usually found in high-risk, low-visibility, or sudden-change areas, including:

• Dead ends or T-intersections

• Highway exit ramps or sharp corners

• Rural roads with sudden bends

• At the end of long straightaways where the road abruptly changes direction

• Low-light or reduced visibility zones (e.g., near hills or tree-lined roads)

The Ontario Traffic Manual (OTM) recommends placing this sign well in advance and sometimes accompanied by flashing beacons for night visibility.

How Should Drivers Respond to the Checkerboard Sharp Turn Sign?

Drivers should respond immediately upon seeing this sign by:

• Reducing speed drastically before reaching the bend

• Steering in the direction of the arrow to safely navigate the turn

• Avoiding hard braking at the last second

• Being extra alert during poor weather or nighttime driving

Disregarding this sign could result in:

• Driving off the road

• Collisions with barriers, curbs, or ditches

• Loss of vehicle control, especially at higher speeds

Visual Representation of the Sign

The Checkerboard Sharp Turn Sign is one of the most visually striking warning signs on Canadian roads—and for good reason. It helps prevent severe accidents at abrupt road endings or curves. Whether you’re taking your Ontario G1 driving test or navigating rural roads, understanding and responding to this sign is essential for safe and legal driving.
