An Garda Síochána and the Road Safety Authority (RSA) are urging people to be safe on the roads this bank holiday weekend.
They are also being reminded that the clocks are going back, bringing darker days.
Road-users are asked to ensure they can be clearly seen when out on the roads.
The most effective way to do this is to wear high visibility clothing - such as a high viz vest or a Sam Browne belt - when walking, cycling or motorcycling and by ensuring you have working lights on your bicycle, motorcycle and car.
Over the past five years, six people have been killed and 33 people have been seriously injured during the October bank holiday weekend.
People are being asked to 'be safe and be seen', particularly on poorly-lit rural roads.
A study conducted by the RSA in November 2015 monitored the high visibility wearing rates of 3,990 motorcyclists and 17,637 pedal cyclists.
It found that 58% of motorcyclists were observed wearing high visibility clothing, an increase of 21% when compared to 2014.
While 50% of pedal cyclists wore high visibility clothing, and wearing rates were more prevalent among private cyclists (54%) than cyclists using public bike schemes (33%).
To help drivers stay alert behind the wheel, the RSA and Applegreen will provide free cups of coffee to drivers between 2.00pm and 8.00pm on Friday October 28th and Monday October 31st at participating service stations.
People should simply say "RSA" or "Driver Reviver" to the till operator to avail of a free coffee.
Transport Minister Shane Ross said: "The evenings will get much darker from this weekend on, so it is even more important that pedestrians, cyclists and motorcyclists wear high visibility clothing when out on the road. Don’t put your life, or the lives of others, at risk by making it difficult for other road-users to see you."
Moyagh Murdock, chief executive of the RSA, said: "It is very encouraging to see that high visibility wearing rates are increasing among motorcyclists and cyclists.
"It really is critical that road-users ensure they are visible to others on the road, every time they go out for a walk, cycle or on the bike."
To date this year, 159 people have been killed on Irish roads - an increase of 32 when compared to the same period last year.
