The public are being warned by the RSA and Gardaí to take extra caution on the roads after two men lost their lives yesterday.
A man in his 20's died in a single vehicle crash in Mayo yesterday, while a motorcyclist was killed in a collision in Leitrim.
The two incidents bring the total number of people killed on Irish roads so far this year to 97.
The August Bank Holiday is one of the busiest times of the year, with thousands commuting for the long weekend.
New RSA figures also revealed that 10% of motorists say they've drank and drove in the past 12 months.
Garda Chief Superintendent Aidan Reid says "The amount of young person's being detected for driving under the influence are just not listening. On average we are arresting 740 persons per month. There is huge Garda activity out there, and still people are taking chances."
