The number of speeding fines paid by drivers increased by 9% last year.
According to freedom of information figures released to Newstalk, more than €20 million worth of penalties were settled in 2018 and 2019.
If you drive over the speed limit, you get three penalty points and a fixed-charge fine of €80, which increases to €120 if you don’t pay within 28 days.
Just over 110,000 speeding fines were paid in 2018, coming to more than €9.6 million.
But both figures rose sharply last year, when almost 120,000 fines were paid – with the gardaí collecting over €10.5 million as a result.
17% of last year’s fines were in the six Garda divisions in Dublin.
Kildare is the next highest – nearly 13,400 speeding fines were paid last year, coming to nearly 1.2 million euro.
Aisling Reid, a member of the Parc Road Safety Group, said the increase in speeding on Irish roads is very concerning.
She said: "Many of our families have lost family members to speed on the roads.
"Speed is a factor in up to a third of road fatalities every year, so the message really needs to be gotten out there: if you speed, you can cause serious harm or fatalities on the road."
Penalty points are issued with every speeding fine, and there was a similar increase last year.
123,000 penalty point notices were issued for these offences in 2019 - over 10,000 more than in 2018.
