Speed cameras deployed across the country
Speed cameras will be rolled out across the country tonight to catch motorists driving too fast.
Gardai revealed the cameras will be mounted where speed caused a death on the road.
The aim of the scheme is to change driver behaviour and to cut the number of speed-related collisions.
Almost 200 people have been killed on Irish roads so far this year.
Joe Costello, Labour Party spokesman on transport, said the cameras would play a significant role in helping to save lives rather than entrapping drivers as a revenue-raising mechanism.
"The message that every death on our roads is one too many cannot be overstated," he said.
"There is no doubt that excessive or inappropriate speed is a major factor in road traffic collisions."
A map of locations where the safety cameras will be operated is available on www.garda.ie.
John Twomey, Assistant Commissioner for Traffic, appealed to road users to familiarise themselves with these sections of the road network.
"We also appeal to motorists to always drive at an appropriate speed, to reduce the likelihood of being involved in a fatal or serious collision," he added.
