Advisory Speed Limit – 50 km/h

Introduction

The 50 km/h yellow advisory speed sign informs drivers of a recommended maximum speed under ideal driving conditions. Unlike regulatory speed limit signs, advisory signs serve as guidance—especially useful when navigating curves, exits, or other specific conditions that may not be obvious at high speeds. Understanding this sign is essential for G1 learners preparing for safe, cautious driving in Ontario.

What Does This Sign Mean?

This sign indicates:

• The suggested speed limit is 50 km/h

• It applies to particular road conditions such as curves, ramps, or construction zones

• It is not legally enforceable like a white regulatory speed sign but still strongly advised for safety

Design details:

• Yellow background with black numbers

• Rectangular shape with “km/h” below the number

Where Is This Sign Typically Placed?

You’ll usually find this sign:

• Before sharp turns or bends

• On highway off-ramps or on-ramps

• In construction zones where reduced speed is safer

• Near residential or rural areas with narrow roads or limited visibility

How Should Drivers Respond?

• Reduce speed to or below 50 km/h

• Adjust further if road conditions are poor (e.g., rain, snow, fog)

• Recognize that this speed helps maintain control around curves or uneven road sections

• If you’re a G1 or G2 driver, follow advisory speeds closely to meet test and safety expectations

Visual Representation

This sign features large black numbers (“50”) and “km/h” text on a bright yellow background, making it highly visible and distinguishable from white regulatory signs.

Conclusion

While not a legal limit, the 50 km/h advisory speed sign is a critical safety indicator. It alerts drivers to upcoming conditions that warrant slowing down—even if the posted speed limit is higher. For new drivers and G1 test candidates, respecting these signs shows good judgment, which is key to passing your road test and driving safely across Ontario.
