Met Eireann has warned of hazardous driving conditions following the issuing of a nationwide snow-ice warning.
The Status Yellow alert was issued as wintry showers battered parts of the country on Monday night.
Temperatures plunged to as low as -2C overnight, which added to the treacherous road conditions as icy patches began to form.
AA Roadwatch has also warned motorists to take extra care when making journeys on Tuesday.
A spokesman said: "Icy road conditions have been reported in many areas this morning, particularly in parts of the west and north of the country.
"Particular caution is needed on higher ground and in sheltered spots."
And Brokers Ireland has advised motorists of small practical steps to help get safely through the poor weather and avoid accidents.
Director at the organization Cathie Shannon says drivers should familiarize themselves with the detail of their car insurance policies.
She added: "It’s advisable to ensure your phone is fully charged in case you may need to call for assistance.
"Cold weather can decrease tyre pressure. It’s also important to know that front-wheel drive vehicles have greater grip, they handle ice and snow better than rear-wheel drives.
"Rear-wheel drive cars are more prone to skidding. Carrying weight in your boot can help somewhat by putting additional weight on the back tyres."
She added: "Worn tyres are particularly hazardous in ice and snow."
Here are seven safety measures, from Brokers Ireland, which you should take note of when driving on ice or snow:
- Not to use very hot or boiling water to clear windscreens, as it can crack the glass
- Check the car’s coolant or antifreeze levels
- Clean lights and make sure they are working
- Keep fuel topped up to cover long delays
- Remember stopping distance can be increased ten-fold during ice and snow, so make allowance for that
- Carry a winter survival kit, including a high-vis jacket and reflective warning triangles
- Be ever more conscious of, and generous to, pedestrians, cyclists and other road users.
