New Winter Driving Requirements
Winter driving in Colorado has always been challenging, but this year drivers will need to pay more attention to the contents of their trunk. A new law requires all two-wheel-drive vehicles to carry snow chains during I-70 travel from September 1 to May 31. This move places passenger cars under the same control that has long applied to commercial trucks.
Explanation from the Department of Transportation
The Colorado Department of Transportation emphasizes that this does not mean banning two-wheel-drive cars from driving in the mountains. It only means they must treat chain requirements the same way long-haul truckers do.
Chain Law Takes Effect
When weather changes, truck drivers must stop and install chains. Now the same will apply to front-wheel-drive or two-wheel-drive vehicles.
The law is in effect on the segment between Dotsero and Morrison, although CDOT and CSP can activate it on other highways during storms.
Conditions for Applying Requirements
Although the traction law is formally in effect all winter, the requirement to install chains applies only when CDOT and CSP declare conditions severe enough. This means two-wheel-drive vehicles don’t need to constantly have chains on, but they must be prepared to use them.
It was added that CSP is not expected to set up checkpoints to verify chains, but police officers will inquire about them if they stop a vehicle.
Consequences of Non-Compliance
At a minimum, drivers of front-wheel/two-wheel-drive vehicles must have traction enhancement devices for at least two wheels. Non-compliance results in a $50 fine plus additional fees, and drivers who block traffic due to unpreparedness face fines of up to $500.
It’s important to note that all-wheel-drive vehicles are also not exempt from similar preparation. They must use winter or all-weather tires, or M+S tires with a minimum tread depth of 3/16 inch.
Recommendations for Drivers
Those who do not meet these standards may also be fined. CDOT directs drivers to new online guides that show how to install chains, what to bring, and how to stay safe on I-70. This corridor is known for unpredictable weather, steep grades, and heavy traffic.
As a former Colorado resident and frequent visitor, I can say that sometimes the weather changes dramatically in less than an hour. Being prepared is most important, and now it’s legally mandatory for everyone on the road.

These legislative changes reflect growing concerns about road safety during winter conditions, especially on key highways like I-70. Chain and tire requirements can significantly reduce weather-related accidents and delays, which is particularly important for regions with rapidly changing weather. Preparing drivers for unexpected winter conditions is becoming not only a matter of personal safety but also of public responsibility.
