Three Lanes of Traffic (One With, Two Against) Sign – W083 | Permanent Ireland Traffic Sign

Three Lanes of Traffic (One With, Two Against) Sign – W083 | Permanent Ireland Traffic Sign

The Three Lanes of Traffic (One With, Two Against) Sign – W083 | Permanent Ireland Traffic Sign is designed to warn drivers that the road ahead features a three-lane configuration, with two lanes of oncoming traffic and only one lane in the driver’s direction. This setup is common on rural national roads, where overtaking opportunities are limited and traffic volume is uneven between directions.

The symbol displays one upward arrow alongside two downward arrows on a yellow diamond background, visually representing the unequal directional flow. This sign is essential for lane discipline and overtaking awareness, especially in situations where misjudging the layout can lead to head-on collisions.

This layout is addressed in Chapter 6 of the Traffic Signs Manual (TSM) and is often seen in transition zones from dual carriageways to single carriageways or shared overtaking lanes.

Technical Review

The W083 sign is manufactured to full EN12899-1 standards and conforms with all relevant TSM 2024 regulations. It offers enhanced clarity at critical sections of roadway where lane allocation changes, and helps prevent dangerous manoeuvres in shared zones.

The sign should be installed in advance of the lane transition, allowing time for vehicles to adjust positioning, avoid overtaking, and prepare for merging or yielding as necessary.
