Construction Zone Begins Sign

Introduction

Construction areas require extra attention, reduced speed, and heightened caution due to workers, equipment, and lane changes. The Construction Zone Begins Sign is a regulatory sign used across Canada, marking the official start of a designated roadwork area. This sign is legally enforced and part of the Ontario G1 driving test.

What Does the Construction Zone Begins Sign Mean?

This sign indicates that you are entering an active construction zone, and new rules may apply. It features:

• Black uppercase text: “CONSTRUCTION ZONE BEGINS”

• White rectangular background with black border

• Sometimes paired with reduced speed limit or worker presence signs

The moment you pass this sign, construction zone laws—including speed fines—are in effect.

Where Are These Signs Typically Placed?

They are used at the entry point of a construction or maintenance zone, often found:

• On highways, city roads, or bridges

• Before active construction, lane shifts, or resurfacing areas

• At night or during off-peak repairs with portable setups

• Near utility work, painting crews, or temporary closures

The sign may also be accompanied by flashing lights, cones, or flaggers.

How Should Drivers Respond to This Sign?

Upon entering a construction zone:

• Immediately reduce speed to the posted limit (often 40–60 km/h)
