Before driving a mountain route in winter, what should you check regarding chain requirements?

Pick an answer

1. Whether the route requires tire chains under certain conditions, and that you're carrying the right chains if so
2. It's only necessary to check chain requirements once you're already on the mountain grade, which surprises a lot of drivers new to requirements
3. Chain requirements only apply to passenger cars, not commercial vehicles
4. Chains are never required on any public highway in the United States
