Sign name	Additional Lanes Joining From Right - Left Joining Lane Continues (Two to Three Lanes)
Sign type	Others Signs
Expected in DTT?	Yes. This sign is commonly covered in Irish driving theory test preparation.
Action required	This sign indicates a two to three lane expansion where a new lane joins from the right while the existing left lane maintains continuous flow without disruption. Drivers in the left lane can continue their journey unimpeded while being aware of merging activity to their right. This design prioritizes through traffic continuity while accommodating increased capacity. The configuration supports efficient traffic distribution and prevents disruption to established traffic flow patterns during capacity increases.
Appearance	Rectangular / Blue and white
Typical location	Left lane continuation signs during right lane additions are positioned on Ireland's dual carriageway network where traffic flow prioritizes left lane continuity including N7 Naas Road sections, M4 western approaches to Dublin, regional dual carriageways near Cork and Limerick, and other areas where capacity expansion accommodates slip road integration while maintaining through traffic flow. These configurations ensure continuous flow for existing traffic while safely accommodating additional vehicles from junction approaches and slip roads.
