No Right Turn

No Right Turn signs appear at junctions throughout urban Ireland where right turns would create dangerous crossing movements across oncoming traffic or cause congestion.

Common at Dublin junctions including O'Connell Street/Abbey Street, Dame Street intersections, and along Luas Red/Green Line crossings where right turns would cross tram tracks dangerously.

Frequent in Cork city center on Patrick Street, in Galway near Eyre Square, and in Limerick's one-way system.

Many restrictions are time-based during peak hours (7am-10am, 4pm-7pm) shown on supplementary plates.

Right turns are absolutely prohibited at this junction.

You must proceed straight ahead or turn left if permitted.

Prohibitions exist where right turns would: require crossing multiple lanes of heavy traffic creating collision risk, cross tram lines at dangerous angles, enter areas with conflicting traffic movements, or cause unacceptable delay to traffic flow.

Time-based restrictions reflect peak hour congestion concerns—right turns may be permitted evenings and weekends.

The prohibition applies to all vehicles including motorcycles and emergency vehicles not on active calls.

Even with green arrow signals showing, if a No Right Turn sign is present, the prohibition overrides signals.

Violating No Right Turn signs constitutes failure to comply with mandatory traffic control signs: €80 Fixed Charge Notice and 3 penalty points.

Violations causing collisions with oncoming traffic while making prohibited right turns result in careless or dangerous driving charges: fines to €5,000, 5 penalty points, and full civil liability.

Many prohibited right turn junctions have camera enforcement in Dublin, Cork, and Galway—automated detection systems issue postal notices with photographic evidence.

Violations near Luas crossings carry enhanced penalties due to tram collision risks.

Accumulating turn prohibition violations results in license reviews.

Turn prohibition recognition is fundamental to theory and practical test success.

Theory questions test understanding that red circular signs are mandatory prohibitions, knowledge that turn restrictions manage traffic flow and safety, and recognition that supplementary time plates modify restrictions.

Practical tests in urban areas specifically include junctions with turn prohibitions to assess sign observation skills.

Examiners expect early recognition allowing appropriate lane selection, correct interpretation of time-based restrictions, and alternative route planning.

Violating turn prohibitions results in immediate Grade 3 failure demonstrating dangerous lack of sign awareness.

Poor lane selection due to late sign recognition results in Grade 2 faults.
