Met Eireann has issued a yellow weather warning for snow and ice for tonight and much of tomorrow morning.
Showers of snow are expected at times, particularly on hills, mountains and areas of high ground in the western half of the country.
Temperatures are likely to fall below freezing nationwide tonight and hazardous driving conditions should be expected.
When travelling in ice and snow, drivers are reminded to watch out for “black ice”, use dipped headlights, decrease speed smoothly and leave extra distance between them and the vehicle in front.
Pedestrians and cyclists are advised to wear a high visibility jacket or reflective armband.
