I am not at all familiar with the ticket disputing process, but regardless of whether you plan on disputing, I think the most important thing is to find out definitively what violation you have been written up for. There may not be any point to go by what the officer told you if he had booked you up for something else. And since there is no Section 2.9(1) in the MVAR, and Section 2.9 in the MVA refers to something totally different, I think your first order of business is to confirm that.
