What does a Give Way line require a driver to do in Northern Ireland?

A Give Way line requires you to give priority to traffic on the road you are joining or crossing and proceed only when it is safe.

Unlike a Stop sign, it does not automatically require the wheels to stop if the junction is visibly clear, but you must slow enough to assess it properly.

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 does a Give Way line require a driver to do in Northern Ireland?” — the practical point is: Look for cyclists, motorcycles and pedestrians as well as cars, and be prepared to stop completely if necessary. 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.
