158 people died on Irish roads in 2017, 15% less than deaths recorded in 2016.
The latest Road Safety Authority statistics also reveal last year was also the safest year on Irish roads since road deaths were first recorded in 1959.
Previously, 2015 with 162 deaths, was the safest year on record.
“It is very encouraging to see that we have reversed the upward trend in road deaths witnessed in 2016", said Transport Minister Shane Ross.
"But while it is heartening to see that 2017 was the lowest year on record for road deaths, this is not good enough. We need to continue our efforts if we are to achieve the objective of reducing fatalities to 124 by 2020"
"Ultimately our aim should be zero deaths on our roads.”
