What is the Maximum Authorised Mass of a vehicle?

  • Both operators and drivers need to take care with the maximum authorised mass of any vehicle they are operating or driving.  The Maximum Authorised Mass, or Gross Vehicle Weight as it is also known, is the maximum carrying capacity of the vehicle; this is the vehicle when it is full of diesel along with all the passengers and driver.  It may be possible to overload a vehicle where heavy wheelchairs are carried or where the payload is small.  For more information please see our Advice Note on Minibuses and Overloading available in the Registered Users area of the Advice and Information section.

    Where any of the above conditions cannot be met, the driver will need to pass a second driving test in a minibus including, medical and theory, hazard perception and practical tests.  This will gain them a full PCV D1 entitlement.
