Overtaking rules in Ireland

Overtaking safely requires good judgement of speed, distance and road markings. The theory test checks that you know where overtaking is permitted and where it is prohibited.

Key facts to remember

  • A continuous white line on your side of the centre means you must not overtake.
  • A broken white centre line means overtaking is allowed when it is safe.
  • Never overtake near a bend, brow of a hill, junction, pedestrian crossing or where signs prohibit it.
  • When passing a cyclist, leave at least 1 metre at speeds up to 50 km/h and 1.5 metres above that.
  • Only overtake on the left in slow-moving lanes of traffic or where directed by lane markings.
