Drivers could be facing another hike in toll rates from January.
From this Saturday, the price of using some of the country's main roads will increase by up to 10 per cent including the M50 and the M1
But Transport Infrastructure Ireland has told the Oireachtas Transport Committee it's "highly likely" the rates will go up again next year.
It says an increase in the consumer price index of more than 3 per cent will mean a guaranteed increase in tolls in January.
From July 1st, tolls on the M50 will go up by 30 cent for cars without tags to €3.50, while cars with tags will see a 20 cent increase, and on the M1, M7, M8, N6, N25 and N18, tolls for cars will rise from €2 to €2.10.
The Port Tunnel will see no increase.
