first rule of checking any laws, dont bother calling transport they never know wtf is going on. Its all coming in on July 1, most of the new laws will only affect people gaining their provisional license after July 1 though. You can reference the police to that pdf, but regardless they wont care. The only way you can have a decision by a police officer overturned is in court and as crimpage said if the pdf isn't correct in respect to the law, youve got nothing.
