Motorists urged to drive with caution as freezing temperatures wreak havoc on roads
Reports of black ice across the country
Temperatures reached as low as -4 degrees in parts of the country last night and motorists are being advised to be wary of black ice on the roads this morning.
Drivers are being urged to leave plenty of space between the car in front of them and to avoid braking suddenly.
There are reports of severe frost on the M8 Dublin-Cork road from junction 6 onwards.
Traffic is said to be heavy on the N4 due to a collision inbound after the Liffey Valley junction and also the N11.
Frost is here and ground is slippery. Increase braking and following distances. You won't see the black ice until it is too late #drivesafe— Will Cochrane (@WillDriverC) November 23, 2016

@aaroadwatch worst traffic I've seen on N11 NB (where there's been no crash) in a long time. Very bad thru GOTD to Bray North— Kiera (@littlebird_ie) November 23, 2016
There has been a collision on the M50 northbound between Ballymount and Tallaght exits.
Meanwhile, there are delays of up to 20 minutes for DART and commuter services this morning due to low rail adhesion caused by a number of leaves on the railway lines.
On its website, Iarnród Éireann states: “When leaves fall on to the line, particularly in damp or wet weather, the rolling action of passing wheels compresses them, causing a greasy ‘mulch’ to cover the rail. This mulch is to rails what ice is to roads. It reduces the adhesion between wheel and rail - hence the phrase "low rail adhesion". The leaf mulch can also affect the operation of track circuits.”
Dangerous road conditions look set to continue into the week due to the Arctic snap being experienced by Ireland.
Temperatures are expected to plummet to -6 degrees in parts of the country, particularly in the midlands.
Ice and fog will be widespread over the next few days with freezing fog developing in midland areas.
