Police say the last day of Manx Grand Prix saw four vehicles seized for having no tax - and 11 tickets handed out for speeding.
The Roads Policing unit says the final day of the motorsport festival proved as busy as others over the last two weeks.
Five drivers will be appearing in court for speeding, not wearing a seatbelt, or having no tax or insurance - while another four were given fixed penalty notices.
Officers say they also issued a dozen defect notices for people to fix minor problems.
