Transport Inspectors have the same powers as Police Officers to stop a vehicle, request your name and address and to ensure compliance in accordance with the Vehicle Standards Regulations/Rules and Licensing Regulations. They can also take on road action to prevent the continuation of an offence against these regulations.
Transport Inspectors conduct compliance patrols and roadblocks across the entire State of Western Australia (both metropolitan and regional areas).
Refer to the "What I can expect during a heavy vehicle inspection" brochure.
Information about how and where to pay the infringement is stated on the infringement notice. If payment is not received within the specified time, a reminder notice will be sent (additional fees apply). If payment is still not received the matter will be referred to the Fines Enforcement Registry where negotiation of the payment may be discussed and/or requested (for more information contact the Fines Enforcement Registry). If you believe an infringement has been incorrectly issued, you must submit an appeal in writing to Main Roads Heavy Vehicle Operations Branch or, if you believe you are not guilty of the offence, you may elect for the matter to be heard before a Magistrate (this can be done by addressing such a request to the address listed on the back of the infringement notice before the due date of the infringement).
