Gardaí and the Road Safety Authority have appealed to drivers to take care on the roads over the bank holiday weekend and through the winter months.
Extra checkpoints will be mounted nationwide by gardaí this weekend to ensure drivers are complying with the law.
They will also be targeting learner permit owners, who are obliged to drive with fully-qualified drivers accompanying them.
According to figures released from four enforcement operations this year, 36% of learner drivers were not accompanied in this way, while 26% did not have L plates displayed.
Noel Brett of the RSA said this is the most dangerous time of the year on the roads.
He said clocks turning back, leaves on the roads, wet conditions and dark mornings have all contributed to the difficult conditions.
