Ontario Traffic Manual Book 7: Traffic Control Standards & Safety Complaince
Book 7 of the Ontario Traffic Manual sets the standard for safe traffic control across Ontario. It guides how construction zones, road work, and temporary closures are managed to protect both workers and drivers. This article explains what Book 7 covers, how it relates to OHSA, and why proper training is essential for compliance.
The Foundation of Roadway Safety in Ontario
Every day across Ontario, thousands of workers set up traffic cones, lane closures, and work zones to keep roads functional and safe. Behind every sign and barrier is a set of clear standards designed to protect both workers and drivers.
Those standards come from Book 7 of the Ontario Traffic Manual, the province’s key reference for temporary traffic control.
Whether you are working on a construction site, maintaining utilities, or managing a road closure, Book 7 outlines how to create a safe, visible, and organized work zone.
Understanding and applying its principles is not only best practice—it is a legal and moral responsibility for every employer, supervisor, and traffic control person in Ontario.
What Is Book 7 of the Ontario Traffic Manual?

It forms part of the Ontario Traffic Manual (OTM) series, which establishes consistent road safety rules across the province.
Book 7 is specifically focused on temporary conditions, meaning any time normal traffic patterns are disrupted due to construction, maintenance, or utility work.
Its primary goals are to:
-
Protect workers and road users.
-
Maintain predictable traffic flow.
-
Ensure uniform signage and layout across Ontario.
Book 7 applies to municipalities, contractors, construction crews, and traffic control companies responsible for managing traffic near work zones.
Who Must Follow Book 7?
Book 7 applies to anyone who sets up or works in or near a temporary traffic control zone, including:
-
Construction and road maintenance crews.
-
Utility companies conducting repairs or installations.
-
Municipal and provincial transportation departments.
-
Private traffic control contractors.
-
Traffic control persons (flaggers) and site supervisors.
Compliance with Book 7 ensures that work areas meet both MTO and Occupational Health and Safety Act (OHSA) standards.
Why Book 7 Matters
Traffic control is not just about directing vehicles—it is about saving lives.
Improper signage or poorly managed lane closures can lead to serious injuries or fatalities.
Book 7 provides the framework to:
-
Design work zones that are visible and organized.
-
Use signage that matches standardized formats and colors.
-
Set speed control measures that protect both workers and drivers.
-
Maintain consistent communication between workers and motorists.
Every element of a safe roadway—from a simple cone placement to a full highway detour—starts with the guidance found in Book 7.
Applying and Complying with Book 7 Standards
Main Goals of Book 7
The Ontario Traffic Manual Book 7 has four clear objectives that guide every temporary traffic control plan in the province:
-
Worker Safety: Protect people working on or near roadways.
-
Traffic Flow: Maintain steady and predictable vehicle movement.
-
Signage Consistency: Use standard signs, cones, and barriers so drivers understand what to expect.
-
Public Protection: Safeguard pedestrians, cyclists, and motorists passing through or around work zones.
Together, these goals form the backbone of Ontario’s road-safety framework. Check out our – Ontario Traffic Control Training Course
Key Components and Guidelines
Book 7 provides direction for every stage of a temporary traffic control operation.
1. Work Zone Setup and Closure
Before any work begins, a clear temporary traffic control plan must be created.
It should include lane closure points, detour routes, and safe entry and exit paths for vehicles and workers.
After work ends, the zone must be cleared promptly, with all devices removed once normal traffic resumes.
2. Signage and Devices
Signs must follow MTO-approved symbols, colors, and dimensions.
Typical devices include warning signs, delineators, cones, barrels, and barricades.
Improper or homemade signage is not allowed because it creates confusion and risk.
3. Speed Management
Book 7 outlines how to reduce vehicle speed in work zones using advance warning signs, taper lengths, and buffer spaces.
Temporary speed limits must be posted clearly and restored once the work area is safe.
4. Night Work and Visibility
For evening or low-light projects, Book 7 requires additional lighting, reflective materials, and illuminated signage.
Workers must wear high-visibility apparel that meets CSA Z96 standards to stay visible from all directions.
5. Flagging Procedures
Traffic control persons (flaggers) play a vital role.
They must be positioned where drivers can see them clearly, use standardized hand signals or paddles, and wear approved PPE.
Flaggers should never stand in the direct path of moving vehicles.
Book 7 and the Law
Book 7 supports the Occupational Health and Safety Act (OHSA) by providing the practical steps needed to comply with Ontario’s legal duties for roadwork safety.
-
OHSA: Requires employers to take every reasonable precaution for worker safety.
-
Regulation 213/91 – Construction Projects: Defines specific responsibilities for traffic control, signage, and protective gear.
-
Employer Duties: Employers must assess risks, provide training, supply protective equipment, and ensure that all work zones follow current Book 7 standards.
Failure to comply can lead to enforcement by the Ministry of Labour, Immigration, Training and Skills Development (MLITSD) and potential penalties.
Training Requirements and Certification
Book 7 training is mandatory for anyone who sets up or directs traffic in a work zone.
Training covers:
-
Legal duties under OHSA and Reg 213/91
-
Reading and applying Book 7 diagrams
-
Flagging techniques and communication
-
Work zone design and equipment setup
-
Emergency response procedures
Workers must receive both theory and hands-on instruction and be able to demonstrate competence before working independently.
Refresher training is recommended every three years or whenever Book 7 is updated.
Difference Between Book 7 and Other Ontario Traffic Manual Books
The Ontario Traffic Manual (OTM) contains multiple volumes, each focused on a different aspect of road safety.
Book 7 is unique because it covers temporary conditions, while other volumes cover permanent road design, sign placement, or signal systems.
In simple terms, if road conditions change due to short-term work, Book 7 applies.
How Often Book 7 Is Updated
The MTO periodically revises Book 7 to reflect new technology, safety research, and national standards.
Employers should always confirm they are using the latest version from the Ministry of Transportation of Ontario (MTO) website or approved distributor.
