Gross Train Weight
Gross train weight is the maximum permitted combined weight of a towing vehicle and its trailer, including passengers and load.
What is Gross Train Weight?
It is usually shown on the vehicle’s manufacturer plate. It can be lower than the car’s maximum weight plus its towing capacity added together. Exceeding it overloads the drivetrain and brakes. The figure also limits how heavy a trailer you can tow when the car itself is fully loaded.
How it works
The manufacturer sets the limit based on engine, gearbox, cooling and braking capacity.
Why it matters for your car
Weigh the loaded car and trailer at a public weighbridge if you are unsure. Driving licences may limit the total weight you can tow.
