THE RURAL SPEED LIMIT SIGN
The Rural Speed Limit Sign (RUS 041A) is a sign used as an alternative to the 80 km/h sign face (RUS041) on specific single-lane rural roads (those typically referred to as ‘boreens’) to remove the 'visual target' of the 80 km/h speed limit. The speed limit remains at 80 km/h, however, drivers are encouraged to use their best judgement to drive at speeds appropriate for the road/conditions but no greater than 80 km/h.
Indeed, this advice can be followed for all speed limits - they are not targets.
This sign can only be used single-lane Local Tertiary roads and selected single-lane Local Secondary roads and not on Local Primary Roads, Regional Roads or National Roads (Primary or Secondary)
