Hundreds of drivers have been trapped inside their vehicles in below freezing conditions on the M80 overnight.

At the height of the traffic jam, around 1000 vehicles were at a standstill with tailbacks of around eight miles.

Police and BEAR Scotland have been working overnight to try and get the traffic flowing again.

A red warning remains in place until 10am and an amber warning is in place until 6pm, with the public advised not to travel.

Superintendent Helen Harrison said: "We are now 24 hours into the red and amber-related advice not to travel on the roads and rush hour last night was noticeably less busy thanks to people heeding our message.

"It remains the same this rush hour coming - do not travel.

"Many of those people who did go out yesterday faced treacherous conditions, blocked roads, being stuck in their vehicles or even being involved in collisions.

"We do not want anyone to put themselves or others at risk in these conditions."

People were taking to social media to report being trapped.

One woman wrote on Twitter: "A 20 minute commute has taken me over nine hours!"

Traffic Scotland reported this morning that the M80 northbound at J8 and southbound between J9 and J8 remains closed.

The M73 at Junction 2 is also closed.

Police Scotland have urged people not to drive this morning unless it is an emergency.

A red weather warning remains in place for central Scotland until 10am.

Transport minister Humza Yousaf said: "The travel advice in the affected areas today could not be clearer - do not travel unless it is absolutely necessary to do so.

"Even after the red warning is lifted, large parts of Scotland will still be subject to high level amber weather warnings for snow.

"This should not be underestimated.

"An amber warning means there is a real possibility that vehicles and drivers will become stranded - something that we have already seen happen during this period of snow.

"I strongly urge people to adhere to police advice by avoiding travel in areas with red and amber warnings.

"I also encourage employers to be as flexible as possible with their staff, allowing them to stay safe and avoid travel."

Almost 30 councils, including Edinburgh City Council, Glasgow City Council and Fife Council, have closed their schools for a second day.

Flights at major airports have been disrupted, with Glasgow and Edinburgh cancelling all flights until 11am and 12pm respectively.
