With vehicle braking performance comprising such an important part of the annual test (MOT), the DVSA is reminding all operators that they must bring HGVs to test with a load.

To carry out the brake test effectively, it is necessary for the vehicle to be loaded to 65% of its design axle weight, the Driver and Vehicle Standards Agency (DVSA) explained.

“You can supply the load yourself or the Authorised Testing Facility (ATF) may be able to supply ballast for you,” it has told operators. “There may be a charge for this, so it is best to check with the ATF first.”

The DVSA is working with the Traffic Commissioners to highlight the importance of laden brake testing and will be issuing further information and reminders in the weeks ahead.

At the moment it is referring operators to Heavy Vehicle Brake Test: Best Practice, which was published in 2016, and further information is available in Understanding your HGV or Trailer’s Brake Test Report.

The latter report highlights that operators should get their HGV or trailer’s brakes tested by a roller brake tester (RBT) at least four times per year, including at the MOT. It also recognises that a number of vehicles are not able to be presented in the laden condition due to basic design limitations, or restrictions caused by the type of cargo they normally carry (including livestock and perishable liquids).
