Police dealt with more than 70 collisions across Lincolnshire since 7am.
Many minor roads are closed due to heavy snow, with police teams and volunteers working together to rescue stranded vehicles.
In particular, the A46 between the Carholme and Riseholme roundabouts in Lincoln is closed in both directions after lorries came to a halt on the hill.
Motorists in the area have been held up for several hours on the A46.
