As the Deputy will be aware, under the Garda Síochána Act 2005 (as amended) the Garda Commissioner is responsible for the management and administration of Garda business, including all operational policing matters. This includes all matters related to road traffic enforcement. As Minister I play no role in these independent functions.
Additionally, the Deputy will be aware that Road Traffic legislation rests under the remit of my colleague, the Minister for Transport.
I am advised that there is no legal requirement for speed camera warning signs to be in position prior to the operation of speed camera vans in an area.
