What the issuing authority is alleging

  • The vehicle, location, date and time alleged on the PCN
  • That the relevant restriction was in force at that location
  • That the evidence supports the contravention described by the code

Evidence to review

  • All pages of the PCN and any later notice
  • Date, time, location and vehicle-registration details
  • Council photographs or video stills
  • Relevant signs, road markings and bay or zone layout
  • Traffic Regulation Order or scheme order where needed

Points requiring investigation

  • Check whether the PCN description matches the code and any suffix actually printed on the notice.
  • Review whether the signs, lines or scheme terms at the location support the alleged restriction.
  • Check whether the authority evidence covers the full period or manoeuvre that matters for this code.

Common misunderstandings

  • A suffix is contextual and does not always mean the same thing for every base code.
  • A short stop can still be alleged if the restriction prohibits stopping rather than parking.
  • A belief that the restriction was unfair is different from evidence that the alleged contravention did not occur.
