Glossary
Road slippery conditions are a condition with low slip resistance due to insufficient road friction. It is a result of snow, ice, water, loose material, and the road surface structure on the traction produced by a vehicle's wheels.
Keep in mind that the road can be slippery even if it is a few degrees above zero or two, without there being clear signs of ice. There may also be an extra high risk of slippery conditions on bridges or in viaducts.
