Ramps could be introduced on roads across Monaghan to clamp down on excessive speeding.
In a recent traffic survey by the Ballybay Clones MD, one driver was clocked doing more than three times the 50 km/h speed limit on the Scotshouse to Clones Road.
Traffic speed counts were carried out on the Ballybay, Threemilehouse and Cootehill roads approaching Newbliss, in Drum Village and on the Scotshouse Road out of Clones.
The number of speeding violations ranged from 47 per cent in Drum to 87 per cent in Clones.
Executive engineer Colin Murphy said the results can't determine what direction the vehicles were travelling, and a margin of error should be considered on the figures, but would be close to actual road speeds.
On the Newbliss to Cootehill Road the maximum speed recorded was 97 km/h, 102 in Drum Village and 138 kmh on the Ballybay Road out of Newbliss.
One motorist was recorded travelling at 156kmh between Newbliss and Threemilehouse and 180kmh or almost 112 mph pm the Scotshouse Road out of Clones.
Murphy added that there's evidence to suggest once instance of two vehicles racing when they passed the sensors, and it was suggested that some drivers may have seen the sensors and attempted to record the highest possible speed.
Councillors agreed that traffic calming measures must be introduced to reduce even the lower exceedances and that they'll reissue a letter to local Gardaí to call for assistance in road safety monitoring.
Councillor Hugh McElvaney suggested, and it was supported by others that the use of speed ramps specifically be considered on the surveyed roads with it said ramps are the "only thing that slows down traffic".
