Can PSNI issue a fixed penalty for stopping on a motorway in Northern Ireland?

Yes. PSNI lists stopping on a motorway among offences for which an endorsable fixed penalty can be issued.

Motorway stopping is tightly restricted because of the danger. Genuine emergencies and places where stopping is specifically permitted are treated differently.

With PSNI or NIRSP paperwork, use the reference number on the notice and meet the deadline printed on that document. Keep copies of what you send. A fixed penalty, NIP and request for driver information are different legal steps, so do not ignore one because you intend to dispute another. For "Can PSNI issue a fixed penalty for stopping on a motorway in Northern Ireland?", read the notice itself before acting because the response route depends on whether it is a NIP, driver-information request, course offer or fixed penalty.
