A Category 1 Traffic Management Plan BC submission may be less complex than a Category 2 or Category 3 plan, but it is not simply a generic traffic-control drawing. Contractors must still confirm the project category, identify the correct road authority, assess site-specific risks, prepare a Traffic Control Plan, and include any additional sub-plans required by the project conditions.
Incorrectly assuming that a small or short-duration project is automatically Category 1 can lead to revisions, permit delays, remobilization costs, and changes to the planned work window. This guide explains how Category 1 classification works, what documentation may be required, how municipal requirements can differ, and what contractors should verify before submitting or implementing the plan.
What Is a Category 1 Traffic Management Plan BC?
A Traffic Management Plan, or TMP, is a project-specific document that explains how workers will be protected and how motorists, pedestrians, cyclists, transit users, emergency vehicles, and other road users will move through or around a work zone. Under the BC Ministry of Transportation and Transit’s Traffic Management Manual for Work on Roadways, projects are classified as Category 1, Category 2, or Category 3. Category 1 projects generally create minimal impact on the travelling public. They are commonly associated with simple terrain, two-lane roads or highways, and lower traffic speeds or volumes.
A Category 1 project may involve work such as minor utility maintenance, short-duration civil work, roadside repairs, shoulder activity, or limited lane impacts on a lower-volume roadway. However, project type or duration alone does not determine the category. The final classification must consider the roadway, traffic volumes, speed, lane configuration, work-zone length, detours, duration, pedestrian and cyclist activity, transit operations, emergency access, overlapping work zones, and other site-specific hazards. A Category 1 Traffic Management Plan BC document should therefore be treated as a complete site-specific plan, not as permission to use a simplified or reusable template without proper assessment.
How Is a Project Confirmed as Category 1?
The BC Traffic Management Manual uses a three-stage Project Category Determination process.
1. Initial Project Category Assessment
The initial assessment reviews the physical and operational characteristics of the project. Factors include posted speed, peak-hour traffic volume, number of lanes, the location of work, lane or intersection closures, detours, project duration, anticipated delays, and impacts on pedestrians, cyclists, bus lanes, or other road users. Under Table 3.1 of the TMM, an initial score below 16 indicates an initial Category 1 assessment. A score from 16 to 25 indicates Category 2, while a score above 25 indicates Category 3.
This is only the first stage. An initial Category 1 score does not automatically make the final project Category 1.
2. Project Risk Analysis
The risk analysis considers hazards that may not be fully represented in the initial scoring. These can include restricted lane widths, equipment storage, changing road surfaces, vehicle queues, access to businesses or public facilities, transit stops, overlapping projects, emergency facilities, and unusual work activities. Each project has a different combination of risks. The TMM therefore allows an evaluator to increase the risk level when a significant project-specific hazard is not adequately captured by the standard table.
3. Final Project Category Determination
The initial category and risk result are combined to establish the final category. An initial Category 1 project can remain Category 1 when its risk is low or medium. If the risk analysis produces a high-risk result, the final classification is upgraded to Category 2. This is why contractors should not describe a project as Category 1 merely because it lasts one day or affects a local road. The complete assessment must support the classification, and the road authority has the final say regarding the documentation and mitigation measures it will accept.
Getting this classification right matters because an incorrect category may require the Traffic Management Plan to be redesigned after submission. That can affect permit processing, planned mobilization, subcontractor scheduling, equipment bookings, and overall project cost.
What Must a Category 1 Traffic Management Plan BC Include?
The BC TMM requires a Category 1 plan to identify the road authority, describe the work activity, document the work location and work-zone size, identify affected lanes, state proposed delay or closure periods, describe site hazards, and explain how identified impacts will be mitigated.
A complete Category 1 Traffic Management Plan BC package normally addresses the following components.
Project Category Determination
The submission should show how the project was assessed using the TMM process. It should identify relevant roadway and traffic conditions and demonstrate why the final result is Category 1. Municipalities may require the completed determination as a separate submission document. For example, Abbotsford requires Project Category Determination for every Traffic Management Plan submission and uses it to determine whether additional plans or professional authentication are needed.
Traffic Control Plan
A Traffic Control Plan is required for Category 1 projects on provincial roadways. It explains how traffic will be controlled and should show:
- Applicable speed management
- Temporary sign and device placement
- Device spacing and maintenance
- Work-zone limits
- Travel-lane configuration
- Accesses and intersections
- Direction of traffic
- A north arrow
- Modifications made to the selected TMM layout for actual site conditions
The drawing may reference a typical TMM layout, but it must still be adjusted to match the real road, work activity, visibility, traffic pattern, and surrounding facilities.
It is important to distinguish between a Traffic Control Plan and a traffic control person. The drawing is required, but a traffic control person is not automatically required for every Category 1 site. The TMM hierarchy first considers elimination, engineering controls, and scheduling before relying on traffic control persons where other controls are unsuitable.
Incident Management Plan
An Incident Management Plan is required when the road authority identifies hazards that could affect the travelling public or when special accommodation is needed for emergency vehicles. It is also recommended where the work zone is longer than 100 metres with restricted travel lanes, where hazards require additional mitigation, or where a total road closure is planned for any duration. The plan should identify emergency contacts, response procedures, access through the work zone, and any additional information required by the authority.
Public Information Plan
A Public Information Plan explains how upcoming traffic impacts will be communicated to the road authority, affected stakeholders, and the travelling public. Under the provincial TMM, it is recommended when a highway will be closed for more than 10 minutes or when work occurs on a two-lane roadway carrying more than 500 vehicles per hour in the affected direction. Communication measures may include project information signs, notices to nearby properties, road-authority updates, transit coordination, or dynamic message signs.
Implementation Plan
A Category 1 Implementation Plan is required when an Incident Management Plan is used. It identifies who is responsible for implementing and supervising the Traffic Management Plan, such as the site supervisor, Traffic Control Supervisor, and traffic control persons, when applicable. Municipal authorities may also request an Implementation Plan based on duration, operational complexity, or local risk.
Professional Engineer Authentication
A Professional Engineer is not automatically required for every Category 1 plan. However, the road authority may request authentication when the work presents significant risk, unusual duration, complex staging, sensitive structural elements, or substantial potential impact on workers and the public. Abbotsford’s current guidelines explicitly state that Professional Engineer authentication may be required for Category 1 and Category 2 submissions, while it is required for Category 3 projects. Not sure whether your project is truly Category 1 or whether additional sub-plans are required? Have the project conditions reviewed before submission to reduce avoidable revisions.
Common Category 1 Traffic Management Plan Mistakes That Cause Delays
Calling a project “low risk” is not enough to support a Category 1 classification. The plan must demonstrate why the classification and selected traffic-control measures are appropriate.
Assuming Short-Duration Work Is Automatically Category 1
Short-duration work receives a lower value in the initial assessment, but it is only one factor. A single-shift project can still involve high traffic volumes, a busy intersection, a transit route, restricted visibility, pedestrian facilities, or emergency access. When these conditions increase the project risk, the final category may be upgraded.
Submitting a Generic Traffic Control Drawing
A standard TMM layout is a starting point, not a finished plan. The final Traffic Control Plan must reflect the actual road alignment, speed, work-zone position, driveway access, intersections, lane widths, equipment activity, sidewalks, bike routes, and other site conditions. A drawing that could apply to any street does not demonstrate that the contractor has assessed the real work zone.
Confusing the Traffic Management Plan With the Permit
The Traffic Management Plan explains how traffic and work-zone risks will be managed. A highway use, excavation, street-use, lane-closure, or other road-occupancy permit provides the legal authorization for the activity. Submitting a Traffic Management Plan does not replace the relevant permit application. Contractors should identify both the controlling authority and the required permit before finalizing the plan.
Using the Wrong Road Authority’s Requirements
The TMM is the primary framework for Ministry roadways and is also used or referenced by many municipalities. Municipalities can add local requirements for lane widths, parking, transit, work hours, public notices, road closures, and submission procedures. Projects crossing municipal and provincial jurisdiction may require coordination with both authorities and more than one permit. Abbotsford’s guidelines specifically warn that additional permits may be needed where work affects both municipal and provincial roads.
Overlooking Pedestrians, Cyclists, Transit, and Property Access
A low vehicle impact does not mean that other road users are unaffected. Closing a sidewalk, bike lane, bus stop, driveway, or accessible parking area can create a significant operational or accessibility issue. The plan should show how these users will receive a safe, practical, and clearly signed route. Where an existing accessible facility is affected, the temporary arrangement should provide functionally consistent access.
Ignoring Non-Active Work Conditions
Conditions can change after workers leave. Signs that no longer apply may need to be covered, turned, or removed. Excavations, stored equipment, barriers, narrow lanes, and temporary surfaces may still require delineation. Abbotsford requires separate Traffic Control Plans for active and non-active conditions for each traffic scenario. This is a local requirement, but it demonstrates why contractors must check what the relevant municipality expects rather than relying only on a daytime setup.
Avoid discovering these issues after the review has started. A project-specific pre-submission check can help identify missing layouts, sub-plans, and jurisdiction requirements earlier.
Designing a Practical Category 1 Traffic Control Plan
A Category 1 plan should be simple only where the site itself is simple. The design must still provide clear and positive direction to every approaching road user.
Work-Zone Layout and Devices
The drawing should identify the advance warning area, transition area where applicable, buffer space, work activity area, and termination area. Signs, cones, drums, barricades, delineators, temporary markings, and other devices should be selected and positioned according to the current TMM. Unnecessary devices should not remain in place. The TMM warns that the misuse, overuse, or deficient use of traffic-control devices can create additional hazards. Its Category 1 template instructs users to turn or remove unnecessary signs as soon as possible. The plan should also explain how signs and devices will be inspected, corrected, and maintained throughout the work.
Pedestrian, Cyclist, and Transit Accommodation
Category 1 work can still occur beside sidewalks, multi-use pathways, bicycle lanes, transit stops, and school routes. The plan should identify whether these facilities remain open, require a temporary alignment, or need a signed detour. Municipal requirements may be more detailed than the general TMM framework. Abbotsford, for example, requires lane widths of at least 3.0 metres for its Traffic Control Plans and at least 3.3 metres on transit routes. It also requires accessible temporary transitions when pedestrian facilities are closed. These are Abbotsford-specific standards and should not be presented as universal BC rules.
Traffic Control Persons and Supervision
Traffic control persons must have training acceptable to WorkSafeBC when they are used. The employer remains responsible for ensuring effective traffic control wherever traffic could create a hazard to workers. The plan should clearly identify who will supervise traffic control, who may change the field layout, how personnel will communicate, and what happens if actual traffic conditions differ from those assumed in the plan. Field staff should not make significant unrecorded changes simply because the original drawing is inconvenient. Changed conditions should be assessed, documented, and communicated to the road authority where required.
Road Authority, Permit Timelines, and Cost Factors
The first administrative step is confirming who controls the affected road. For a provincial highway, the responsible authority will generally be the BC Ministry of Transportation and Transit. For a municipal road, the city or municipality will normally control the road-use permit and may apply additional traffic-management standards. The road authority can modify submission expectations based on the project and local conditions. Therefore, there is no single Category 1 submission process, permit timeline, or fee that applies uniformly across British Columbia.
For example, Abbotsford’s August 2025 guidelines require at least seven days between initial submission and planned work. Complete submissions are generally reviewed within seven days, while incomplete information and significant revisions may extend the review or require the process to restart. These timelines are specific to Abbotsford and should not be assumed for another municipality.
The cost of a Category 1 Traffic Management Plan BC project can be influenced by:
Number of traffic scenarios: Different construction phases, lane arrangements, and active or inactive conditions can require separate drawings.
Additional sub-plans: Emergency procedures, public notifications, transit coordination, or implementation details increase the required work.
Professional authentication: A road authority may require a Professional Engineer when the project has unusual or elevated risk.
Permit and notification requirements: Fees, public notices, dynamic message signs, parking restrictions, and transit arrangements vary by authority.
Revisions: Incorrect classification, missing information, or major scope changes can require redesign and resubmission.
There is no reliable province-wide Category 1 fee table. Contractors should confirm local permit fees and submission requirements directly with the controlling authority.
Category 1 Traffic Management Plan Implementation, Inspections, and Daily Records
Acceptance of the document is not the end of the traffic-management process. The field setup must match the accepted plan, and the plan must remain effective as the work changes. When the TMM Category 1 template is used, daily updates are required through the Daily Sign Check Form. The form records inspection times, locations, deficiencies, comments, and corrective actions.
Before work begins each day, the responsible supervisor should verify that:
- The correct traffic scenario is being implemented.
- Signs and devices are positioned, visible, clean, and stable.
- Travel lanes and temporary routes remain usable.
- Pedestrian, cyclist, transit, and property access match the plan.
- Emergency access is available.
- Unnecessary signs from inactive conditions are removed or covered.
- Weather, visibility, queues, or site activity have not created a new hazard.
- Deficiencies and changes are recorded and corrected.
The TMM treats a Traffic Management Plan as a dynamic document. Changes to work activities, schedules, traffic arrangements, or the Traffic Management Plan itself may require amendment and resubmission to the Ministry for review and acceptance.
Daily documentation also provides evidence that the contractor actively inspected and maintained the work zone rather than relying only on the original drawing.
How Plan My Traffic Supports Category 1 Projects in BC
Plan My Traffic prepares project-specific traffic planning documents for contractors carrying out roadwork, utility work, development activity, construction access, maintenance, and other temporary roadway operations in British Columbia.
For a Category 1 Traffic Management Plan BC project, the process begins by reviewing the location, road authority, work activity, duration, traffic impacts, available drawings, work hours, and affected road users.
The project information is then used to:
Confirm the appropriate planning scope. The available road, traffic, and work-zone information is reviewed before the project is treated as Category 1.
Prepare site-specific drawings. Traffic-control layouts are developed around the actual lane configuration, access points, road geometry, work area, signs, and devices.
Identify additional documentation. Incident response, public notification, implementation details, or professional authentication are considered where project risk or local requirements justify them.
Address municipal variations. Applicable local requirements are incorporated rather than assuming every BC municipality applies Category 1 in exactly the same way.
Support implementation. The completed plan is organized so contractors and field personnel can understand the intended traffic scenario and their responsibilities.
The objective is not to guarantee acceptance. It is to provide clear, complete, and project-specific documentation that supports road-authority review and practical on-site traffic management.
Conclusion
A Category 1 Traffic Management Plan BC submission may cover a simpler site, but it still demands a full assessment of roadway conditions, traffic volumes, pedestrian and cyclist activity, and site-specific hazards before the classification can be confirmed. Treating Category 1 as a shortcut or relying on a generic layout overlooks the real risks a project may carry, and the consequences show up later in the form of revisions, remobilization, and added cost. Contractors who verify the road authority, complete the full Project Category Determination, and prepare a Traffic Control Plan matched to actual site conditions put themselves in a stronger position from the first submission. Getting the classification and documentation right from the outset keeps a project moving smoothly through review and out onto the road.

Frequently Asked Questions
1. Is every short-duration roadwork project considered Category 1?
No. Short duration is only one factor in the Project Category Determination. Traffic volume, speed, lane closures, detours, road geometry, pedestrians, cyclists, transit, emergency access, and site-specific risks must also be assessed. A high-risk result can upgrade an initially Category 1 project to Category 2.
2. Does a Category 1 Traffic Management Plan BC always require a Traffic Control Plan?
A Traffic Control Plan is required for planned Category 1 work on or near provincial roadways. Municipalities may also require one for every project. The drawing must identify the selected traffic-control layout, devices, speed management, work-zone configuration, north arrow, and site-specific modifications required for the actual location.
3. Does Category 1 always require traffic control persons?
No. A Traffic Control Plan is required, but traffic control persons are not automatically necessary at every Category 1 site. The TMM hierarchy prioritizes elimination, engineering controls, and administrative controls. Traffic control persons are used when those methods cannot manage traffic safely and effectively.
4. Does a Category 1 Traffic Management Plan BC need a Professional Engineer’s seal?
Not automatically. However, a road authority may require Professional Engineer authentication where the project has significant risk, unusual duration, complex staging, structural components, or substantial impacts. Contractors should confirm this before submission because the requirement can vary between provincial and municipal authorities.
5. Can the same Category 1 Traffic Management Plan BC be reused at another location?
A previous plan may provide a formatting reference, but it should not be reused without a new site assessment. Road alignment, speed, traffic volume, lane width, accesses, transit, pedestrians, cyclists, work activities, and municipal requirements can differ. Every Traffic Management Plan should reflect the specific project and controlling road authority.
