New data shows 40% of road deaths have taken place on 'R' roads this year.
Majority of fatal road crashes this year have happened on regional roads.
Analysis of statements from An Garda Síochána also shows motorways account for the least amount of fatal crashes.
It comes after a man in his 30s lost his life in a single vehicle collision on the R420 between Geashill and the Cloncollig Roundabout in Tullamore last night.
Up to this morning, there have been 83 fatal crashes, resulting in 98 deaths.
Of those incidents, just under 40% happened on regional or ‘R’ roads.
That was followed by national roads, which accounted for 31% of crashes.
Around a quarter happened on 'L' roads, which are the roads in which speed limits were reduced to 60 kilometres an hour back in February.
Leo Lieghio from the IRVA says that was the right move, but more enforcement is needed:
Meanwhile, two deaths happened on motorways - both on the M50.
Garda have put up a number of static and average speed cameras, majority of which have been on national roads.
But the force stresses that some of these deaths may be reclassified at a later stage, and so this data is just preliminary.
