1. Overview

Most commercial vehicles must be tested every year to make sure that they are roadworthy and follow regulations. This is known as the annual test.

As well as the annual test, your HGV must be tested if you want to be able to:

  • carry explosives or dangerous goods in bulk - this is known as the ADR test
  • take goods vehicles outside the EU - this is known as the TIR test
  • ‘uprate’ or ‘downrate’ your vehicle to change the weight it’s allowed to carry
  • qualify for a Reduced Pollution Certificate (RPC) or Low Emissions Certificate (LEC)
