Ireland
1. Mandatory direction
A mandatory-direction sign requires drivers to travel only in the direction or one of the directions indicated by its arrow or arrows. It may require traffic to continue straight ahead, turn, or pass an obstacle on a specified side.
The sign does not itself determine priority or speed. Drivers must still use the appropriate lane, signal when required and give way according to local traffic signs and regulations.
What does a mandatory-direction sign require in Ireland?
Where a compulsory-direction sign is installed in Ireland, follow only the arrow direction or permitted combination of directions. The restriction applies at the location or movement it regulates; it is not an instruction to ignore other traffic controls.

Can I choose another turn if the mandatory-direction arrow is inconvenient in Ireland?
No, unless another applicable sign, lane instruction or authorised traffic direction lawfully permits it. Plan a permitted alternative route; do not make an abrupt or prohibited turn to reach your destination.

Does a mandatory-direction sign give me priority over pedestrians in Ireland?
No. It tells you which way to move, not who goes first. Check traffic lights, other priority signs, pedestrians and cyclists, and give way when required before completing the manoeuvre.
