The cost of using toll roads around the country increased from midnight, when price hikes took effect.
The increases impact nine tolls across the country – eight operated under a Public Private Partnership (PPP) model, as well as the M50.
There will be no price increase for the Dublin Port Tunnel.
Transport Infrastructure Ireland (TII) previously confirmed there will be a 10c price hike at tolls on the M1, M7, M8, N6 and the Limerick Tunnel, increasing the charge to €2.10.
The same amount will also be added on the M3, brining the cost to €1.60, while 20c will be added for the M4, increasing the cost to €3.20.
Cars using the M50 without tags will now be charged an extra 30c, brining it to €3.50, while those with video accounts will see a 20c increase, rising to €2.90. Cars with tags will also have 20c added to the cost of a trip, raising the price to €2.30.
The increases come six months after the Government deferred the hikes in response to the spiralling cost of living.
