More average speed cameras could be brought in to help deal with the surge in road deaths.
It’s one of a number of measures Gardaí are calling for in response to the rise in road fatalities.
There have been 165 deaths on Irish roads this year – bringing the death toll above the total last year of 155.
The rise has led to calls for a greater Garda presence on the roads.
Garda Commissioner Drew Harris told the Oireachtas Justice Committee he wants to see more static and average speed cameras on the road.
"I understand the point you're making in terms of shooing first in a barrel, but this is also about behaviours on the road," he said.
"It's not for the individual driver to decide, 'This is a clear stretch of road, there's not many accidents here, therefore the speed limit is only advisory'.
"There's a lot of single vehicle collisions which are ending up fatalities.
"Very often they are a result of excess speed," he added.

She said the Dublin Metropolitan Region saw largest reduction in the road units, but that is not where crashes have been.
"A lag in recruitment, competing demands with other resources - everything from community policing all the way to the various specialist units that we have," she said.
"There is a requirement for all of those units and we have a finite amount of resources.
"I wouldn't like to give the impression that just because the Roads Policing Units have shrunk somewhat in numbers that it has anyway lessened our focus or commitment to road safety," she added.
The committee also heard that more than 646 members of An Garda Síochána were subject to violence and assault while performing their duties between January and September this year.
