The Irish School of Motoring is adding its voice to the criticism of the new 30 kilometre per hour speed limit introduced in Dublin city centre this week.
The AA, business groups, taxi drivers and motorists have all come out against the move, which is in place in areas around the city, from Bolton Street on the northside to St. Stephen's Green on the southside.
There are also reports that the limit may be introduced in Cork and Galway
Donal Healy from Cork Business Association is opposed to the idea.
"We take pride in the fact that we have 6,500 retail outlets in Cork," Mr Healy said.
"We want people to come in and enjoy the city but if they are not able to access it because of everything slowing down, people will not bring their car in."
