An ADR licence is the certificate that is required by the driver in addition to your driving licence if you wish to drive vehicles carrying hazardous goods.

There is a very long list of substances including packing and other terms and conditions that defines when an ADR licence is and is not required.

Vehicles operating under ADR conditions may be identified by the large orange rectangle carried on the front and rear of the vehicle.

An ADR licence qualifies you to undertake commercial driving work that may attract higher rates of pay commensurate with the extra responsibilities carried by the driver.
