If you manufacture or modify trailers in Australia, you’ve probably heard about drawbar certification. But understanding the process — and meeting all compliance requirements — is essential to getting your trailer legally on the road.
 

At Quantech Design, we specialise in trailer drawbar certification under the Australian Design Rules (ADR62/02), using advanced Finite Element Analysis (FEA) and decades of mechanical engineering expertise to ensure your towing equipment is safe, compliant, and ready for production.
 

What is drawbar certification?

Drawbar certification is the process of proving that a trailer’s drawbar (the structural connection between the trailer chassis and the towing vehicle) meets the strength and safety requirements set by ADR62/02. Under the Road Vehicle Standards Act (RVSA), this certification must be completed through the ROVER online portal for approval before the trailer can be sold or used on Australian roads.

The process generally involves:

• Design review – confirming the drawbar meets ADR specifications.

• Engineering analysis – often using FEA to test structural integrity under load.

• Documentation preparation – compiling design drawings, analysis results, and compliance statements.

• Submission to ROVER – for assessment and approval.
   

Without certification, a trailer cannot be legally registered, meaning this step is essential for manufacturers and modifiers.
 

Which trailers require certification?

ADR62/02 applies to most trailers with an Aggregate Trailer Mass (ATM) up to and over 4.5 tonnes. This includes, but is not limited to:

• Boat trailers

• Car carriers

• Caravan and camper trailers

• Agricultural trailers

• Industrial and plant equipment trailers

• Heavy-duty transport trailers
   

If your trailer is towed on public roads, chances are it falls under ADR62/02 and requires drawbar certification.
