Here is a typical example of a vehicle's VIN plate. It may also be displayed as a sticker on one of the vehicle's door pillars.
Take a look at the weights stamped in kgs -
2720kg - Maximum Authorised Mass (MAM)
6220kg - Gross Train Weight (GTW)
The last two weights refer to maximum axle weights -
1 = Front, 2 = Rear.
Calculating a vehicle's towing capacity from the VIN plate -
Using the VIN plate in the image, we can determine what this particular vehicle's towing capacity is by simply subtracting the MAM weight from the GTW weight.
- In this case; 6,220 - 2,720 = 3,500kg
- The maximum towing capacity of the vehicle this VIN plate belongs to is 3,500kg.
NOTE: - It has been known for V5 log books to be printed incorrectly. If in doubt, contact your local dealer and check the weights displayed on the vehicle's VIN plate itself (that's what the Police / DVSA Enforcement will use if you are stopped on the road).
