8. An authorised examiner or any other person authorised by the Registrar shall not be required to carry out an examination of a motor vehicle in any of the following cases:
where on the submission of a vehicle for an examination the applicant for the examination does not, after being requested to do so, produce the registration document relating to the vehicle or any other evidence as to the date of its first registration or the inspection report, where applicable;
where the vehicle or any part thereof or any of its equipment is in such a dirty condition as to make it unreasonably difficult for the examination to be carried out;
where the examiner or authorised person is not able, with the facilities and apparatus available to him at the vehicle testing station at which the examination would otherwise be carried out, to complete the examination without the vehicle being driven and the vehicle is not, when submitted for examination, provided with fuel or oil to enable it to be driven to such extent as may be necessary for the purposes of carrying out the examination;
where before the carrying out of an examination of the motor vehicle all or any goods or other things which are on the vehicle and are not part of its equipment or accessories are required to be removed from the vehicle or to be secured in such manner as the examiner or authorised person may think necessary and the goods or things are not removed or secured accordingly.
