Road Narrows on Both Sides

Road Narrows on Both Sides signs appear throughout Ireland where construction encroaches from both edges reducing overall road width.

Common on N and R roads during barrier installations affecting both sides, extensive utility works occupying verges bilaterally, and bridge approaches where abutment work restricts width from both directions.

Found where temporary narrowing affects entire width rather than single-side encroachment.

These indicate bilateral width restriction requiring all drivers to adjust regardless of lane position.

Common during Ireland's extensive rural road improvement projects where modern safety features are retrofitted to narrow traditional routes.

Road width is reduced from both left and right sides creating overall narrowing affecting all traffic.

Reduce speed to 50 km/h or as posted and position vehicle carefully in center of narrowed section.

Enhanced attention required as clearances are tight on both sides simultaneously.

Large vehicles may need to slow significantly or stop to ensure safe passage.

On single-carriageway roads, prepare to yield to oncoming traffic if narrowing doesn't accommodate two-way passage.

Bilateral narrowing often more restrictive than single-side narrowing as no wider side exists for positioning adjustment.

Continue through narrowed section until normal width restoration is clearly indicated.

Excessive speed through bilateral narrowing zones results in €120-€300 fines with 2-3 penalty points recognizing restricted clearances.

Collisions with barriers or equipment on either side in clearly posted narrow zones result in full liability with fines up to €2,000.

Failure to yield in narrowed sections where two-way passage impossible results in €80-€120 fines.

Large vehicle operators proceeding without ensuring adequate clearance face enhanced prosecution.

Courts recognize bilateral narrowing as clearly warned restriction requiring appropriate speed and positioning adjustments with violations indicating deliberate risk-taking.

Bilateral road narrowing requirements are covered in Irish theory tests as common rural and urban construction scenario.

You must understand that both-sides narrowing requires central positioning, significant speed reduction to 50 km/h, and readiness to yield if two-way passage impossible.

Theory questions test recognition that bilateral narrowing is more restrictive than single-side narrowing, understanding of appropriate speed adjustments, and yielding requirements on single-carriageway sections.

Practical assessments evaluate proper speed control, accurate vehicle positioning in bilaterally narrowed sections, and appropriate yielding behavior.

Demonstrating bilateral narrowing understanding shows readiness for Ireland's extensive road improvement and maintenance activities.
