A total of 13 people lost their lives on Irish roads last month, the lowest number of deaths since records began in 1969.
According to provisional figures from the Road Safety Authority (RSA), 176 people have died as a result of traffic incidents so far this year, a decline of 42 deaths from the same period a year earlier.
Previously, the lowest number of roads deaths per month occurred in February 2009 when 15 people died.
The latest monthly total is in stark contrast to November 1981 when a total of 80 people lost their lives on Irish roads.
Minister for Transport Noel Dempsey welcomed the latest figures, saying that the introduction of tougher penalties had contributed to Ireland becoming the sixth safest country in Europe.
"The introduction of the penalty points system, mandatory alcohol testing, the Garda Traffic Corps and the reform of the driver licensing system are just some critical elements of the Government's Road Safety Strategy that have had a dramatic and positive effect on road safety. The decision to introduce these changes saved lives," said Mr Dempsey.
"Lives have been saved and devastating injuries prevented. With continued commitment and leadership there is absolutely no reason why Ireland cannot be the very best in Europe. It can be done," he added.
