The cost of car insurance has fallen by up to 20%, according to independent research commissioned by the Automobile Association.
A reduction in the number of accidents brought about by the introduction of the new penalty points system was given as one of the main reasons for the decrease in premiums.
Other reasons given include the amount of settlements undertaken and an overall reduction in compensation amounts.
However, the AA has indicated that there is still some way to go - with legal costs still a major issue.
According to the motoring body's public affairs manager Conor Faughnan: "The priority now is to enforce the system more.
"It is absolutely essential that the Government should keep its promise and establish a dedicated Garda Traffic Corps. The gains made in terms of road safety and reduced insurance premiums will not be sustained if the Government fail us by not addressing the enforcement issue," he added.
The AA first commissioned Catalyst Market Research to perform a study on car insurance in April this year by contacting what is termed a 'mystery shopping' exercise.
The same research was performed months later allowing for comparisons to be made.
