Traffic Authority Inspection: Why Is It So Important?

A traffic authority inspection isn't just another audit. It's the inspection that can shut down your site. The local traffic authority is the body that approved the traffic management plan, and it can revoke that approval if field conditions don't meet requirements. Shutting down a site means delays, costs, and sometimes fines.

The good news: a traffic authority inspection is predictable. Most requirements are known in advance, and if you prepare the site properly - there's no reason to worry. This guide will walk you through it step by step.

Step 1: Documents That Must Be Ready

Approved Traffic Management Plan

This is the first document the inspector will request. Ensure you have the latest approved version, signed by the traffic planner and approved by the authority. If there have been changes since the original approval, ensure those are also approved in writing.

Traffic Authority Permit

The permit must be valid. Check start and end dates. If the permit has expired, renew it before the inspection - a site operating without a valid permit is a serious finding.

Police Consultation Protocol

Not required at every site, but if applicable, ensure the protocol is available. If not relevant to your site, prepare an explanation why.

Safety Consultant Inspection Reports

The inspector will want to see that a traffic safety consultant conducts regular inspections. Ensure the latest reports are available, organized, and current. If there are open deficiencies from previous reports, know the status of each one.

Step 2: Sign Survey

Go into the field with the plan in hand and check sign by sign:

900 Series Signs

These are the dedicated work site signs. Ensure every sign required by the plan is actually placed, in the correct position and at the correct height. Check specifically: Sign 901 (road works warning) at the work zone entrance. Sign 908 (directional arrow) at required locations. Sign 915 (warning and instruction board) with appropriate text. And Sign 916 (work zone speed limit) with the correct speed per the plan.

General Signs

Ensure general signs required by the plan are present and functional. Watch for signs displaced by works or damaged by heavy equipment.

Stability and Visibility

Every sign must be stable (not fallen, not tilted), clean, legible, and not obscured by vegetation, equipment, or vehicles. A fallen or tilted sign is a finding recorded immediately.

Step 3: Guardrail Inspection

Review every guardrail line on site:

Are guardrails positioned exactly per the plan? Are all sections continuously connected? Are energy absorbers or end terminals installed at the beginning and end? Are reflectors placed continuously in the direction of travel? And is fencing on the guardrail complete and not protruding into the travel lane?

Note: A guardrail damaged by a vehicle impact and not repaired is a serious finding. If there's a damaged guardrail - repair before the inspection or document that you've requested repair and when.

Step 4: Road Markings and Cat's Eyes

Road Markings

Verify that temporary road markings in the field match the plan. Ensure old markings have been removed as required and new markings are clear and visible. The inspector will compare what's written in the plan to what's actually painted.

Cat's Eyes

Ensure delineators are placed per the plan, clean, and reflective. If there's a night inspection - this is where the inspector will check meticulously.

Step 5: Road Surface and Infrastructure

Road Surface Cleanliness

Ensure the road surface is clean of sand, gravel, construction debris, and oil. If needed, order mechanical sweeping the day before the inspection.

Potholes and Cracks

Damaged road surfaces endangering vehicle stability are findings requiring immediate treatment. If there are potholes or cracks - repair or mark with warning signs.

Emergency Bays

If required by the plan, ensure they're free of obstacles, marked, and accessible.

Step 6: Pedestrian Crossings and Accessibility

The inspector will check all routes pedestrians are supposed to use. Ensure:

Walking path is clear and continuous without obstacles. Directional signage is clear. Accessibility for people with disabilities (minimum 130cm clear passage width, standard ramps up to 8% grade). Curbs are functional with accessible ramps. And adequate lighting if the site operates during dark hours.

Step 7: Supporting Equipment

Arrow Board (Mobile Flashing Panel)

If an arrow board is required, verify: board and light functionality. Valid permits and licenses. Valid insurance. And certified operator.

Lighting and 932 Signs

If the site operates at night, ensure all lighting points are working and 932 signs are flashing as required.

Traffic Signals

If there are traffic signals at or near the site, ensure they're functioning properly, synchronized, and clearly visible to drivers.

Step 8: Address Open Deficiencies

Before the inspection, review all open deficiencies from previous inspection reports. For each deficiency, do one of three things: fix it before the inspection (preferred), document that you've requested a fix and what the status is, or prepare an explanation for why it hasn't been addressed and when it will be.

A traffic authority inspector understands that not everything is perfect at every moment. What they expect to see is a system: that problems are identified, addressed, and tracked.

Step 9: Prepare the Team

Ensure the right people are available on inspection day. The site foreman should know the plan and be able to answer questions. The safety consultant should be available (by phone at minimum). And traffic controllers, if required, should be on-site with vests and credentials.

Quick Checklist for the Day Before

Here's a short list to review the day before:

Documents: approved plan, valid permit, latest inspection reports - ready and accessible? Signs: all in place, stable, clean, matching the plan? Guardrails: continuous, connected, with energy absorbers and reflectors? Markings and delineators: clear, matching plan, old markings removed? Road surface: clean, no dangerous potholes, bays clear? Pedestrians: path clear, accessible, lit, with signage? Open deficiencies: all addressed or documented with status?

How Technology Helps Prepare for Inspections

A digital safety management system like WorkSafety.io significantly eases inspection preparation. All reports are available instantly with complete history. Open deficiencies are centralized in one dashboard with statuses and dates. You can generate a site status summary at the click of a button. And the organized documentation itself impresses the inspector before they even start checking.

If you're preparing for an inspection and have an organized system - you're already in a good position. If not - maybe it's time to start.

Summary

A traffic authority inspection doesn't have to be a stressful event. With proper, systematic preparation, you can pass it with confidence. The key is not to wait for inspection day, but to manage the site at a level that meets requirements at all times. That way, every inspection turns from a threat into an opportunity to demonstrate professionalism.
