Gardaí and the Road Safety Authority are urging motorists to take care over the bank holiday weekend, and to keep a particular look out for motorcyclists.
Five people died on the country's roads over the May bank holiday weekend last year.
Five motorcyclists have died in crashes so far this year compared to two over the same period last year.
Drivers are being urged to constantly be on the lookout for motorcyclists.
Motorcyclists are asked to be extremely careful when overtaking, when negotiating bends and to be particularly mindful of their speed.
Figures show a greater number of motorcycle fatalities over the summer months in 2013 and 2014 due to good weather.
Minister for Transport Paschal Donohoe has appealed to all road users, ahead of the bank holiday, to take extra care when using the roads.
"The May bank holiday weekend was a very bad weekend for road safety last year.
"We lost five lives and six people sustained serious injuries over that four day period. I would appeal to everyone to be mindful of how you use the road, whether you are walking, cycling, riding a motorbike or driving," he said.
Assistant Commissioner John Twomey of the Garda National Traffic Bureau said: "Members of An Garda Síochána will be out in force over the Bank Holiday Weekend to keep the roads safe from careless and dangerous drivers."
