How to Notify the Traffic Commissioner

As an operator or transport manager in the road haulage or HGV industry, it is essential to be aware of your responsibilities when it comes to notifying the Traffic Commissioner. Promptly notifying the Traffic Commissioner is not only a legal obligation but also a crucial step in maintaining compliance and demonstrating your commitment to road safety. In this blog, we will walk you through the process of notifying the Traffic Commissioner and provide a sample formal letter to guide you. We will use an example of receiving a PG9 Prohibition Notice on a vehicle within your possession.

Understanding the Notification Requirement:

The law states that if you receive a PG9 Prohibition Notice on a vehicle that is in your possession as an operator or transport manager, you must inform the Traffic Commissioner as soon as possible and, in any case, within 28 days from the date of issue of the prohibition notice.

This requirement applies to all vehicles covered under your operator’s licence, including those that are hired or borrowed.

Composing the Formal Letter:

When notifying the Traffic Commissioner, it is crucial to do so in a formal manner. Here’s a step-by-step guide to help you draft the letter:

  1. Header: Begin with the official letterhead of your company or organization, including your company’s name, address, and contact information.
  2. Date: Indicate the date on which you are writing the letter.
  3. Traffic Area: Clearly state the Traffic Area in which your Operating Licence is issued. This ensures that your letter is directed to the appropriate authority.
  4. Subject: Use a clear and concise subject line such as “Notification of Prohibition Notice – [Vehicle Registration Number].”
  5. Salutation: Address the letter to “The Traffic Commissioner” followed by the appropriate title (e.g., Traffic Commissioner for [Traffic Area]).
  6. Introduction: In the opening paragraph, briefly explain that you are writing to inform the Traffic Commissioner about the PG9 Prohibition Notice received on one of your vehicles.
  7. Vehicle Details: Provide the vehicle’s registration number, make, model, and any other pertinent details that will help identify the vehicle in question.
  8. Prohibition Notice Details: Clearly state the date and time when the prohibition notice was issued. Include a brief summary of the defect(s) that were found and led to the notice.
  9. Preventive Measures: Outline the specific measures you have taken to ensure there is no recurrence of the issue in the future. These measures could include repairs, maintenance schedules, staff training, or any other relevant actions. Provide evidence to support the effectiveness of these measures, such as receipts, maintenance logs, or training certificates.
  10. Closing: Conclude the letter by expressing your commitment to road safety and compliance with all regulations. Thank the Traffic Commissioner for their attention to this matter.
  11. Signature: Sign the letter personally, or if on behalf of the company, use the name of the authorised signatory and their title.
