Do You Need Snow Chains Right Now? Check the Chain Law for Your Route
Mountain chain laws change by road, weather condition, and vehicle type. Know what’s required before the pass — not at the checkpoint.
Select your state, mountain pass, and vehicle type. The checker returns the current chain law level, vehicle requirements, and penalty for non-compliance.
Chain law violations in active weather carry fines up to $500 and can result in forced stop orders. Some passes fine both directions — entry and exit.
Anyone driving mountain passes in winter, RV owners, and commercial drivers on mountain routes.
