Enforcement of speed limits is happening in the wrong place, a Sinn Féin TD has said.
It follows three deaths on Irish roads across the St Patrick's bank holiday weekend.
There were also five serious collisions with almost 1,800 drivers detected for speeding offences.
One driver was caught doing 209km/hr in a 100km/hr zone on the N3 in Daggan in Co Cavan
Sinn Féin's transport spokesperson Martin Kenny told Newstalk Breakfast reducing speed limits alone is the wrong approach.
"I feel the Government's focus is on a headliner thing where they want to bring down the speed limits," he said.
"An awful lot of the collisions we see happening are not because people are driving within the speed limit and that it's not low enough, [but] that they are driving well in excess of the speed limit and it's not being enforced.
"I think that's the biggest issue we have to deal with".
'Most dangerous'
Deputy Kenny said speed vans need to be on more regional roads.
"The Go Safe vans, we see them here and there around the country, but unfortunately most of the time we see them on motorways or roads leading to the motorway," he said.
"We don't see them on the roads that are most dangerous."
Deputy Kenny said enforcement is just as important as anything else.
"Last year we had the highest number of road deaths in probably the last 10 years," he said.
"This year so far we've had high numbers as well; we've had a lot more collisions happening on our roads..
Deputy Kenny said a lot of these collisions are happening because of speeding on the regional roads.
"A lot of them have a limit maybe of 100km/hr or sometimes 80km/hr and we have people travelling way above that limit," he said.
"We don't have the adequate enforcement in place to ensure that people are caught when they drive recklessly," he added.
Over 9,970 roadside drug and alcohol tests were conducted across the bank holiday which led to 175 arrests for driving under the influence.
