Gardaí are urging motorist to slow down on routes across the region and make extra time for journeys.
The majority of routes across the west are slippery following the mixture of snow and icy conditions.
There are two incidents to report so far this morning – an articulated lorry has been stuck in icy condition on the N17 near Ireland West Airport Knock since around 3:30am this morning.
Elsewhere, there was a single vehicle collision near the dump on the Newport road.
The advice is to slow down and take extreme caution on all routes whether they are treated or not.
