The Village Bakery near Wrexham has laid on 4x4 vehicles to make sure its 180 staff can get into work
North Wales Police say the region appears to be coping with snow which fell in many parts overnight.
The worst affected areas appear to be in south Gwynedd, especially around the Lleyn peninsula.
Fire fighters had to use cutting equipment to free a woman trapped in her car at Boduan near Pwllheli after it hit a wall.
There were also delays on the A55 near Northop earlier on Wednesday after a lorry crashed through safety barriers.
Police have also reported a number of minor accidents on the A483 at Wrexham and Overton.
However, more than a hundred schools have been closed on Wednesday, with Gwynedd, Flintshire and Wrexham seeing the most classrooms shut because of the weather.
Drifting snow has continued to affect some routes in the region, closing some main A routes on higher ground, including the A542 Horseshoe Pass in Denbighshire, the A5104 at Llandegla, Denbighshire, and the A4086 Nant Peris to Pen-y-Pass.
A4086 Nant Peris, Gwynedd, between Market St Llanberis to A498 Pen-y-Pass
A4212 Trawsfynydd, Gwynedd, between A470 and A494 Heol Yr Orsaf, Bala
A5104 Llandegla, Denbighshire, between Llandegla and B5436, Bryneglwys

However, one company, considered to be the highest bakery in Wales, says business has been booming and it has laid on special services to make sure staff can get into work.
The Village Bakery in Minera, Wrexham, is almost a 1,000ft above sea-level and surrounded by around a foot of snow.
The firm has laid on a 4x4 'taxi' service to get staff into the bakery, where it employs 180 staff.
"We're a local bakery in a rural area and we have to be able to cope with these situations - it is winter and sometimes you are going to get snow so you have to be ready for it," said managing director Robin Jones.
"It hasn't always been easy - at a couple of shops down in Churchstoke in Shropshire we couldn't get there but we made arrangements for our delivery van to meet up with a couple of 4x4s to get the bread through and we managed."
