North Yorkshire Police said they responded to more than a dozen crashes in icy conditions between midnight and 9am this morning.
A police spokesman said: “It has clearly been a difficult time on the roads due to the snowfall overnight. Thankfully there have been no serious or minor injury collisions reported during this period, although the dozens of damage-only collisions have kept the emergency and highways teams busy.
“To help keep safe, we urge motorists to drive to the conditions, keep your distance from other road-users and anticipate the longer time it takes to slow down and come to a stop."
During the cold snap drivers are being advised to check their tyre treads, lights, brakes and windscreen wipers and carry water and de-icer with them.
People on long journeys should take food, blankets and a fully-charged mobile phone.
