Understanding Semi / Truck Tire Chain Laws Across All States
Every freight route may look simple on a map, but snow, ice, or mountains can quickly change the game. Tire chain compliance is often overlooked, yet it is critical for safety, schedule reliability, and cost control.
For carriers hauling wide loads, heavy haul, flatbed, dry van, or expedited freight across North America, knowing each state’s chain requirements is essential. At Buchanan Hauling & Rigging, Inc., we’ve built a fleet, trailer network, and compliance culture that thrives in any weather. This guide covers state chain requirements, highlights key states, and explains best practices.
Why Tire Chain Laws Matter for Heavy Haul and Flatbed Carriers
Driving an oversized load over mountain passes or winter corridors requires proper traction. Many states have mandatory seasons, signage, and equipment standards for chains or alternative devices. Missing a chain requirement can cause delays, fines, or detours.
For carriers like Buchanan, crossing into Canada and Mexico adds complexity. Compliance with U.S. chain laws ensures we keep our service promises. Our motto, “Setting the Standard for Safety, One Mile at a Time,” reflects this commitment. See Mission and Values.
