What does a steady amber traffic light mean in Northern Ireland?

A steady amber traffic light means stop at the stop line unless you have already crossed it or are so close that stopping could cause a collision.

Amber is a stop signal, not an invitation to accelerate through before red. The exception is specifically about being too close to stop safely.

For “What does a steady amber traffic light 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 does a steady amber traffic light mean in Northern Ireland?” — the practical point is: Make the decision based on safe braking distance and conditions, not whether you think you can beat the red light. 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.
