Complete Guide to This Sign

Where You'll Find This Sign

Two to three lane expansion signs with right lane additions are positioned on Ireland's expanding dual carriageway network including N7 Naas Road sections, M4 western corridor capacity improvements, regional road upgrades near Cork and Galway, and other developing road infrastructure where capacity increases accommodate growing traffic demands.

These signs typically appear at major junction approaches, urban expansion areas, and sections where slip road integration requires additional lane provision for safe merging and improved traffic flow.

What This Means for Drivers

This sign indicates that road capacity increases from two to three lanes with the additional lane joining from the right side.

Drivers should be particularly aware of vehicles merging from the right, typically from slip roads or junction approaches.

The right lane addition usually accommodates merging traffic while maintaining existing left lane flow.

Drivers should check right mirrors frequently, allow adequate merging space, and avoid sudden lane changes during the expansion area to support safe integration of additional traffic.

Penalties & Legal Consequences

No direct penalties apply to lane expansion notifications, but dangerous driving during right lane merging areas may result in violations: €80-€200 for careless driving affecting merging traffic, enhanced penalties for blocking right lane merging opportunities, potential serious charges for aggressive driving preventing safe junction integration.

Enhanced enforcement may occur at expansion areas near major junctions with automatic monitoring of merging zone safety and traffic flow efficiency.

Appears in Driving Test?

Two to three lane expansion with right merging awareness demonstrates understanding of junction integration and capacity management essential for comprehensive road network navigation competency.

Theory test questions address right lane merging awareness, appropriate space allocation techniques, and junction approach behavior.

Understanding right lane expansion scenarios indicates readiness for diverse road environments requiring adaptive driving and demonstrates comprehensive understanding of infrastructure-based traffic integration essential for safe navigation of Ireland's developing road network.
