Core facts about Lane Gain (Three to Four Lanes, 200m)
Sign name	Lane Gain (Three to Four Lanes, 200m)
Sign type	Others Signs
Expected in DTT?	Yes. This sign is commonly covered in Irish driving theory test preparation.
Action required	Advanced notification that road capacity will increase from three to four lanes in exactly 200 meters, providing drivers with precise distance reference for lane positioning and traffic management. New lane typically forms on left side, creating additional overtaking capacity and reducing congestion on high-volume routes. Drivers should maintain current lane position while being aware that additional space will become available, potentially affecting traffic patterns and merging behavior.
Appearance	Rectangular / Blue and white
Typical location	Lane gain advance warnings positioned 200 meters before capacity increases throughout Ireland's motorway network including M50 orbital approaches to major junctions, M1 northbound before Drogheda interchange, M7 approaching Limerick, M8 Cork approaches, and urban motorway sections where additional lanes accommodate increased traffic volume. Strategic placement allows drivers to anticipate lane formation and adjust positioning safely before new lane becomes available for traffic usage.
