You will need this authorisation if you intend to undertake competency-based training and assessment for drivers to obtain or upgrade their motor vehicle licence. Once obtained you may upgrade your authorisation to include vehicle on road testing (VORT).
Please note that there is currently a moratorium on appointing authorised examiners for Class C (car) vehicles. Motor driving instructors may still apply to become an authorised examiner and can submit reasons in writing why the general policy should not apply to them.
