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
  • That the CCTV or approved-device record shows the alleged movement or stopping event

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
  • Complete CCTV footage, not only still images
  • Approach signs and road markings
  • Route notes showing the vehicle path and lane position

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.
  • Review whether the video shows the approach signage and the full vehicle movement, not just the final position.

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.
  • For moving traffic PCNs, the registered keeper may be liable even if they were not driving.
