What does a temporary STOP/GO board require a driver to do in Northern Ireland?

A temporary STOP/GO board at Northern Ireland roadworks requires you to stop when STOP is displayed and proceed only when GO is shown and it is safe.

For Northern Ireland motorists, the key is to use the NI rule rather than assuming a Great Britain article says exactly the same thing. These boards are part of temporary traffic control, commonly used where one direction is released at a time. The operative may be coordinating with another controller around a bend or obstruction you cannot see.

For this exact issue — “What does a temporary STOP/GO board require a driver to do in Northern Ireland?” — check the live temporary signs first, then confirm the works entry on TrafficWatchNI if you need dates, diversion details or the organisation responsible. Temporary traffic management can alter the normal lane layout, speed limit, access or priority, so an old sat-nav route or memory of the road is not reliable evidence of what is permitted today.

Do not pass the STOP face because the road ahead looks empty. Leave enough space for plant, cyclists and traffic that may still be clearing the controlled section. Where the facts of a journey or vehicle differ from the ordinary case, check the exact DfI/DVA or nidirect rule before travelling rather than extrapolating from a similar situation.

That matters because road rules, licence entitlements and enforcement details can differ from Great Britain and can change over time; the sources attached below are the ones to re-check if the rule is updated.
