Do double yellow lines need a time plate in Northern Ireland?

In Northern Ireland, double yellow lines apply at all times and do not require an upright time plate.

Single yellow lines normally rely on a time plate or Controlled Parking Zone entry signs to show when the restriction operates.

Double yellow lines normally mean the waiting restriction applies at all times, which is why a separate time plate is generally unnecessary.

Northern Ireland has its own DVA licensing system and parking-enforcement rules in several areas, so local nidirect guidance should be checked rather than assuming that every Great Britain rule or process is identical.
