Attaching a Sidecar: Regulations and Considerations at Ausmec Mobile RWC & Mechanics

At Ausmec Mobile RWC & Mechanics, we understand the unique appeal of motorcycles with sidecars. However, attaching a sidecar involves specific regulations and safety considerations. Here's a breakdown of key Queensland Department of Transport and Main Roads (TMR) requirements (https://www.tmr.qld.gov.au/safety/vehicle-standards-and-safety/vehicle-standards/motorcycle-standards) regarding sidecars on motorcycles:

Sidecar Attachment and Approval:

• Simple Bolt-On Sidecars: If your sidecar utilizes a bolt-on design that attaches directly to the motorcycle's frame without requiring any modifications, it may be acceptable without specific approval from the Department of Transport and Main Roads.
• Modified Frame Sidecars: In cases where the sidecar attachment necessitates modifications to the motorcycle frame (e.g., welding), you'll need to obtain approval from the Department of Transport and Main Roads. This process involves engaging a QLD-approved engineer to assess the modifications and submit an application on your behalf. You can find a list of approved engineers in your area on the TMR website.

Sidecar Placement and Width:

• Left-Hand Side Requirement: Generally, sidecars must be attached to the left-hand side of the motorcycle for optimal handling and stability.
• Exception for Older Motorcycles: Motorcycles manufactured before July 1, 1988, are permitted to have a right-hand sidecar configuration if it was originally designed that way.
• Maximum Width Restriction: The combined width of your motorcycle and sidecar cannot exceed 2 meters. This regulation ensures safe maneuvering and avoids obstructing traffic flow.

Additional Equipment Requirements:

• Parking Brake (Post-February 1976 Motorcycles): If your motorcycle was manufactured after February 1976 and you plan to attach a sidecar, it must be equipped with a functional mechanical parking brake. This enhances control and stability when parked.
• Sidecar Parking Light: Your sidecar must have a dedicated parking light positioned within 150mm of the side furthest from the motorcycle. This improves nighttime visibility for other drivers.
