Police are warning drivers to "be extra careful" if travelling in the next 24 hours, after a snow warning was issued for Lincolnshire.
The Met Office has issued a yellow "be aware " weather warning for the county, saying there could be heavy snowfall overnight.
Ch Insp Pat Coates, from Lincolnshire Police, says: "If you don't have to travel, don't travel."
But he added: "If you do have to travel, be prepared" to face heavy snow.
The force is reminding people to continue to follow coronavirus lockdown rules, which say only "essential" travel is allowed.
Officers say they've already dealt with a number of accidents after snowfall this week (pictured).
