I got caught while riding the "segway" (or "hoverboard"), and the policeman told me he will issue a caution or so, and it shouldn't be very high fine because I told him I paid less than $300 for the segway. However, penalty notices were still issued. 1 for unregistered vehicle $650, 1 for uninsured vehicle $650, 1 for not wearing helmet $325. I requested a review online, stating clearly that I never knew this is considered as a motor vehicle and, hence, I never knew this requires registration/insurance/helmet. I'm not knowingly riding an unregistered thing. But they refused to change it to caution and the penalties still apply. So if I request a decision by court, do I need to hire a lawyer? Can they completely dismiss this case, or at least significantly reduce the fine under Traffic Law?
