Before you go
Controls often differ by route, so an R-2 on I-80 doesn’t mean the same on US-50. Check the route you’ll actually drive: I-80 Donner · Highway 50.
What the levels mean: R-1 means chains are required unless you have snow tires; R-2 means chains are required on everything except 4WD/AWD vehicles with snow tires on all four wheels (and those must still carry chains); R-3 means chains on all vehicles, no exceptions.
