How should drivers overtake horse riders in Northern Ireland?

Overtake horse riders slowly, give them plenty of room and avoid actions likely to frighten the horse.

Northern Ireland guidance tells drivers to slow down around animals and not sound the horn. Horses can move unpredictably even with an experienced rider.

This is a vulnerable-road-user question, so the Northern Ireland Highway Code expects drivers to plan for people who may be harder to see, slower to react or more easily injured. The Code repeatedly stresses lower speed, wider clearance, observation and patience around pedestrians, cyclists, children and horse riders rather than treating priority as a licence to press on.

For this exact question — “How should drivers overtake horse riders in Northern Ireland?” — the practical point is: Wait for a wide, clear section, pass gently with generous lateral space and accelerate away gradually. 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.
