What Is a Light Trailer?

A light trailer is defined as a trailer with an Aggregate Trailer Mass (ATM) of up to 4.5 tonnes. These trailers are widely used across residential, trade, commercial, agricultural and industrial sectors.
Whether transporting equipment, vehicles, tools, or materials, light trailers must comply with national and state-based regulations before registration or modification approval. Professional Light Trailer Engineering in Australia services ensure structural safety and regulatory compliance.

Common Light Trailer Types:

  • Box trailers
  • Car and vehicle transport trailers
  • Plant and machinery trailers
  • Trades and service trailers
  • Custom-built light trailers

Key Weight Definitions

  • ATM (Aggregate Trailer Mass): Total mass of the trailer when fully loaded.
  • GTM (Gross Trailer Mass): Mass transmitted to the ground through trailer wheels when coupled.
  • Tare Mass: Unloaded trailer weight.
All light trailers must comply with VSB1, applicable ADRs and state-based transport authority requirements. Our Australian trailer compliance engineering approach ensures every project aligns with these standards.
