The ADI Registrar also issues trainee licences to give instruction. In order to qualify as an ADI, three tests must be passed: theory (part one) - a multiple choice section and a video-based hazard perception section; driving ability (part two) - an eyesight test followed by a practical test of driving technique; instructional ability (part three) - a practical test of the ability to instruct. All three parts of the examination must be passed in this order, and must be completed within two years of passing the theory test (part one). After being entered on the ADI register, ADIs are free to give driving instruction for money or monies worth, either working for a driving school or being self-employed. It is a condition of remaining on the register that all ADIs undergo a periodic "test of continued ability of fitness to give instruction" also known as the 'check test'. The passage of the Road Safety Act 2006 empowered DSA to set the standards on all paid tuition, not just that of motor cars as was previously the case. The DSA required people who applied to register as a Potential Driving Instructor (PDI), as well as existing ADIs who applied to extend their registration or re-register, to have a criminal record check. DSA used the Criminal Records Bureau (CRB) to obtain criminal record checks of people in England and Wales, and Disclosure Scotland for people in Scotland. Some ADIs choose to take additional qualifications so that they can train drivers of large goods vehicles, or fleet drivers. The DSA also held a voluntary register for fleet drivers, Compulsory Basic Trainers (for motorcycles), Large Goods Vehicle instructors and the Register of post-test motorcycle trainers. These registers provided quality standards for the relevant
