Motorists are being warned of severe delays on the motorway following a crash.
Queues are backing up on the M6 northbound from junction 27 at Standish to junction 28 Leyland after a vehicle was blocking the carriageway just south of the Charnock Richard service station after hitting the central reservation.
One lane is also closed on the M58 westbound at junction 5, A577, at Upholland, following an accident.
Highways officers attended up to nine collisions in the region before breakfast-time as heavy rain and snow made conditions treacherous.
A vehicle was on its side on the southbound carriageway of the M61 between Chorley and the Macron Stadium near Bolton, while another was reported to have careered off the motorway and up an embankment in the same area.
And police reported debris on the northbound carriageway of the M61 near to junction 6.
A spokesperson for the North West Motorway Police said the weather was causing problems and urged drivers to “please alter your driving accordingly and slow down.”
