New Colorado Legislation Requires Snow Chains for Certain Vehicles | Carscoops

      A recent change in regulations in Colorado may result in unprepared drivers facing fines this winter, as chain laws are now applicable to regular vehicles.

      Colorado now mandates that front-wheel drive vehicles carry chains during I-70 activations. Drivers lacking chains or obstructing traffic during winter storms may incur fines. Additionally, all-wheel drive vehicles must comply with tread-depth regulations and utilize winter-rated tires.

      Winter driving conditions in Colorado have always posed challenges, but this year, drivers must pay increased attention to their vehicle's preparedness.

      A new law mandates that all two-wheel drive vehicles must carry snow chains while traveling on I-70 from September 1 to May 31, thereby subjecting passenger cars to the same scrutiny typically applied to commercial trucks.

      The Colorado Department of Transportation emphasizes that this law does not prohibit 2WD vehicles from accessing the mountains; it simply means they must adhere to chain requirements similar to long-haul truckers.

      “When weather conditions change, truckers must stop and apply their chains,” stated CDOT spokesperson Andrew Hogle to KDVR. “Now, the same requirement will apply to front-wheel drive or two-wheel drive vehicles.”

      This regulation affects the stretch of I-70 between Dotsero and Morrison, though CDOT and CSP have the authority to activate it on other highways during severe storms.

      While the traction law is technically in effect throughout the winter, the mandatory chain requirement applies only when conditions are declared severe by CDOT and CSP. This indicates that 2WD vehicles do not need to be chained at all times, but they must be equipped to do so.

      Hogle mentioned that CSP does not plan to establish chain checkpoints, but troopers will inquire about chains if they stop a vehicle.

      What Are the Consequences of Being Unprepared?

      At a minimum, front-wheel drive/two-wheel drive drivers must have traction devices for at least two tires. Noncompliance results in a $50 fine plus a surcharge, with penalties reaching up to $500 for drivers who block traffic due to unpreparedness.

      Importantly, all-wheel drive and four-wheel drive vehicles are also subject to similar requirements. They must be equipped with winter or all-weather, or M+S tires that have a minimum tread depth of 3/16 inch.

      Failure to meet these criteria may also lead to fines. The CDOT has directed drivers to new online resources detailing how to install chains, what to bring along, and how to stay safe on I-70, a route known for its unpredictable weather, steep grades, and heavy traffic.

      As someone who has lived in Colorado and visits frequently, I can attest that the weather can change drastically in under an hour. Being prepared is essential, and now it is a legal obligation for all drivers on the road.
