What do rectangular information signs mean in Northern Ireland?

Rectangular signs are mainly used for information, directions and route guidance rather than a single universal instruction.

Their colour and wording matter: different rectangular signs can identify routes, destinations, parking, local facilities or traffic information.

For “What do rectangular information signs mean in Northern Ireland?”, the wider Northern Ireland context is this: Northern Ireland's Highway Code uses signs, signals and road markings together, so the safest reading is always the exact sign at the location plus any lane arrows, plates or temporary traffic management. Rules expressed as ‘must’ or ‘must not’ are legal requirements; advisory wording can still be used as evidence when responsibility for a collision is considered.

For this exact question — “What do rectangular information signs mean in Northern Ireland?” — the practical point is: Do not infer meaning from the rectangular shape alone; read the wording, arrows, colour and any lane diagram before acting. The answer should be applied to the actual signs, conditions, licence wording or parking rules in force at the time, because temporary restrictions and individual DVA decisions can change the ordinary position.
