An identical system has been operational in the Dublin Port Tunnel since 2017. The installation of the system at the M7 sites began on 8 March and will be followed by a period of testing. The roadside equipment will include the yellow poles and cameras traditionally associated with speed cameras and the specific locations have been chosen due frequent hail showers, resulting in increased collision frequency in the area. An Garda Síochána has said no date has been confirmed for the system to go live, but said there will be a formal announcement at least 10 days before the system is operational.
