An Garda Síochána continues to appeal to drivers to comply with speed limits.

Members of the Cavan Roads Policing Unit made a number of detections on the N3 over the weekend.

Gardaí have already detected vehicles breaking the speed limit in the first 2 hours of the major clampdown.

One motorist in Co Monaghan was detected by Gardai within the first two hours of today's road safety initiative.

628 vehicles were travelling in excess of the speed limit during the past 24 hours across the country.
