1. Overview

Commercial vehicles are tested every year to make sure they’re roadworthy and comply with any relevant regulations. This is known as the annual test.

In addition to the annual test, there are extra tests coaches and buses may need to take to:

  • qualify for a lower rate of vehicle tax (commonly known as road tax) by getting a Reduced Pollution Certificate
  • qualify for free entrance to the London low emission zone by getting a Reduced Pollution Certificate or Low Emission Certificate
  • meet seat belt safety rules

From August 2015, you can’t apply for a Pre-Registration Inspection (PRI). You’ll need to get your vehicle approved instead.
