The Keep Straight Ahead Sign – RUS 004 is an essential regulatory road sign used across Ireland to instruct drivers to continue in a straight direction only. This sign is most often installed at intersections, traffic diverges, or at the start of one-way systems where no turning is allowed. Its bold, white upward arrow on a blue circular background makes the instruction clear and unmistakable, even at a glance.

As a mandatory sign defined under Chapter 5 of the Traffic Signs Manual, the RUS 004 ensures traffic flows smoothly and safely in the correct direction. Whether you’re designing urban traffic layouts or managing access on rural roads, this sign is crucial for reducing wrong turns, U-turns, and conflicting vehicle movements.
