Traffic Control Person Ahead Sign

Introduction

In construction zones and areas with temporary traffic flow changes, human guidance becomes essential. The Traffic Control Person Ahead Sign is a temporary warning sign used across Canada to alert drivers that a flag person or traffic controller is ahead managing traffic manually. This sign is part of the Ontario G1 driving test and critical for safe navigation through work zones.

What Does the Traffic Control Person Sign Mean?

This sign indicates that you must be prepared to stop or follow verbal and hand signals from a person directing traffic ahead. It features:

• A black human figure holding a stop paddle in one hand

• An upright arm signaling drivers to stop or slow

• An orange diamond-shaped background, indicating a temporary construction or maintenance zone

This sign warns of human-controlled traffic regulation, not automated lights or standard stop signs.

Where Are These Signs Typically Placed?

You’ll encounter this sign in work or emergency zones where traffic must be manually managed, such as:

• Road construction or paving sites

• Bridge repairs or utility work

• Tree trimming or road sweeping operations

• Emergency vehicle access routes

• Rural or two-lane roads with alternating traffic flow

The sign is posted 100–200 meters before the control zone to allow time to slow down.

How Should Drivers Respond to This Sign?

When approaching this sign:

• Slow down and watch for the person with the stop/slow paddle

• Be prepared to stop when instructed—do not ignore signals

• Do not proceed unless waved forward by the flag person

• Avoid distractions, such as mobile phone use or loud music

• Drive cautiously through the work zone after being allowed to proceed
  Failure to follow instructions can result in:

  • Fines and demerit points under the Highway Traffic Act

  • Endangering workers or causing accidents

  • Immediate road test failure
