Motorists are being warned about hazardous driving conditions following snow fall in many parts of the country yesterday.
A Status Yellow snow-ice warning was put in place by Met Éireann and was valid until 8am.
Caution is urged following widespread frost and some low-lying snow. Met Éireann says that there are some wintry showers, mainly in western areas.
AA Roadwatch says that icy conditions were reported around Carlow town, Naas, Portlaoise, Tullamore, Mullingar, Thurles and Wicklow town.
It has also advised motorists to take particular care on secondary and local routes and on higher ground.
The M7 northbound between Newbridge and Naas is slippery, and caution has been advised. AA Roadwatch says that it may also be slippery on parts of the M9.
It said that the Sally Gap in Wicklow is closed due to dangerous road conditions. Road conditions on routes through the Wicklow Gap are also reported to be very poor.

Meanwhile, Dublin Airport has said that it is open and operational.
However, it says that some airlines are experiencing delays to their flight schedules due to de-icing issues.
It advised passengers to check with their airlines for flight updates.
The weather caused a number of delays and cancellations at the airport last night, with some passengers complaining of waiting on the airfield for more than three hours.
