Chains May Be Required at Any Time
Always carry chains that fit your tires and obey signs to use them. Buy or rent chains outside the parks. Snow tires are also required often, but most cars have them. Check the side of your tires: If you see M / S, M+S, or a snowflake symbol embedded in the rubber, it’s a snowtire.
Expect Icy Roads
Slow down. Watch for ice in shade or where the road looks wet. Sudden speed or stopping causes skids. Keep extra distance between cars.
Clear Snow Off Car Roof & Hood
It may slide onto the windshield, blocking vision.
Plows may operate day & night, moving with or against traffic. If you see one, slow down but do not stop. Watch the plow operator for signals; they often cannot stop. They usually plow 6am–6pm.
Slow Down without Losing Your Brakes
Downshift when going downhill. In automatic vehicles, put the gearshift on 1, 2 or L. The engine gets louder, but it will save your brakes and cause less skidding than braking.
Go Slow for Wildlife!
Animals may run or fly across your path any time. Never feed animals near the road; it makes them more likely to linger and get hit by cars.
Winter Roads & Closures
