Australian Vehicle Tow Calculator

Mastering the Vehicle Tow Calculator for Australian Drivers

Towing safety isn’t just about hooking up a trailer – it’s about precision. In Australia’s vast landscapes where weekend warriors haul boats to coastal towns and families tow caravans across the Nullarbor, getting your towing maths wrong can lead to dangerous situations or hefty fines. Our Vehicle Tow Calculator helps you stay compliant with Australian Design Rules (ADRs) and state regulations.

Why This Vehicle Tow Calculator Matters

Australian law requires drivers to maintain specific weight ratios. The calculator checks three crucial safety factors:

  1. Towing Capacity: Every vehicle has a maximum limit set by manufacturers

  2. Tow Ball Weight: Must be at least 10% of trailer mass for stability

  3. Total Mass: Combined vehicle+trailer weight mustn’t exceed capacity

Step-by-Step Guide for  tow vehicle calculator

  1. Find Your Numbers
    Check your vehicle manual for its towing capacity. Weigh your loaded vehicle and trailer at a certified weigh station.

  2. Input Values

    • Vehicle Mass: Current weight of your loaded car/4WD

    • Trailer Mass: Fully loaded trailer/caravan weight

    • Tow Ball Weight: Measured vertical load on hitch

    • Towing Capacity: From your vehicle’s compliance plate

  3. Get Instant Verification
    Green means you’re good for the open road. Red warnings indicate where adjustments are needed – perhaps redistribute trailer load or remove unnecessary gear.
