Obstruction Between Lanes

Obstruction Between Lanes signs appear on Irish roads where construction equipment, barriers, or work zones are positioned centrally requiring traffic to split around both sides.

Common during median barrier installation on motorways where work occupies center with traffic passing both sides, at central reservation drainage projects, and where overhead gantry foundations are constructed in central areas.

Also appear on wider N roads during central road marking or cat's eye installation work.

These indicate unusual split-flow configuration where drivers must choose left or right path around central obstacle rather than standard lane-following.

Found during Ireland's most complex median infrastructure construction requiring sophisticated traffic management.

A temporary obstruction occupies central area requiring traffic to divide and pass on either left side or right side of the obstacle.

Reduce speed to 50-60 km/h and select appropriate side based on your destination, lane markings, and directional signage.

Enhanced attention required as this creates unfamiliar split-flow pattern rather than standard lane configuration.

Maintain extra spacing from the central obstruction and from adjacent vehicles as clearances may be tighter than normal lanes.

Do not attempt to change sides after committing to left or right path.

Continue past obstruction following temporary markings until normal lane configuration resumes as indicated by signage.

Violations in central obstruction zones carry enhanced penalties reflecting unfamiliar split-flow configurations.

Excessive speed approaching or passing obstructions results in €160-€400 fines with 2-5 penalty points automatically doubled.

Attempting to change sides mid-obstruction results in dangerous driving charges: 5 penalty points, €5,000 fines, and disqualification.

Failure to follow directional signage or temporary markings around obstructions results in €120-€300 fines.

Collisions with central obstructions or other vehicles in split-flow zones result in full liability recognizing clear warning provided.

Workers positioned near central obstructions are particularly vulnerable making violations especially serious.

Central obstruction management represents advanced temporary traffic pattern recognition in Irish theory tests.

You must understand that central obstructions create split-flow requiring early side selection, appropriate speed reduction to 50-60 km/h, and commitment to chosen path without side-changing.

Theory questions test recognition of unfamiliar split patterns, understanding of appropriate side selection based on destination and signage, and enhanced spacing requirements around obstructions.

Practical assessments evaluate early decision-making, smooth side selection, and maintaining proper clearances.

Demonstrating central obstruction understanding shows readiness for Ireland's most complex median construction traffic management scenarios.
