Are Chains Required in Colorado Right Now?
If you're planning to drive through Colorado during the winter months, you might be wondering: Are chains required in Colorado right now? With rapidly changing weather conditions in the mountains, it's essential to stay informed about chain laws to ensure a safe and legal drive.
Current Chain Requirements in Colorado
As of March 3, 2025, the Colorado Department of Transportation (CDOT) has issued chain requirements due to an incoming blizzard on the Eastern Plains and Palmer Divide, along with heavy snowfall in the mountains. Wind gusts up to 70 mph are expected, making travel conditions hazardous.
CDOT has implemented chain laws on various highways, requiring commercial vehicles to have chains on their drive tires. Failure to comply can result in steep fines.
Fines for Violating Chain Laws
$500 fine plus a $79 surcharge for not using chains when required.
$1,000 fine plus a $157 surcharge if your vehicle blocks the highway due to lack of chains.
Mandatory Chain Carrying for Commercial Vehicles
From September 1 through May 31, all commercial vehicles must carry chains when traveling on Interstate 70 between mile markers 259 (Golden) and 133 (Dotsero). Additionally, chain laws may apply on other highways, including:
U.S. 40
U.S. 50 (Salida to the Utah State Line)
U.S. 160
U.S. 285
U.S. 550
Highway 9
What About Passenger Vehicles?
Passenger vehicles are not always required to carry chains, but they must comply with Colorado’s Traction Law during winter storms. This means your vehicle must have:
✅ Snow tires
✅ Tires with a mud/snow (M+S) rating
✅ Chains or an alternative traction device
✅ All-wheel drive or four-wheel drive
If your vehicle does not meet these traction requirements, you could face a $50 fine plus a $17 surcharge.

Final Thoughts
Winter driving in Colorado can be treacherous, especially in the mountains. If you’re traveling through high-altitude areas, make sure your vehicle meets traction requirements, and if you're driving a commercial vehicle, carry the required chains. Not only will this keep you safe, but it will also help you avoid costly fines.
Always check road conditions before heading out, and drive cautiously in snowy and icy conditions. Safe travels!
