Don’t slip up: Colorado expands its “must carry” tire chain law
With winter weather just around the corner, Colorado has enacted a new law that expands the number of highways where tire chains must be carried on commercial motor vehicles (CMVs).
Senate Bill 24-100 requires all vehicles with a gross combined weight rating of 16,001 pounds or more to carry tire chains (or alternate traction devices approved by the Colorado Department of Transportation) on the following highways from September 1 to May 31 of each year:
- I-70 west of milepost 259 (Morrison to Utah state border);
- Colorado Highway 9, milepost 63 to milepost 97 (Frisco to Fairplay);
- Route 40 west of milepost 256 (Empire);
- US Route 50 west of milepost 225 (Salida);
- US Route 160 west of milepost 304 (Walsenburg);
- US Route 285 west of milepost 250 (Morrison); and
- US Route 550 from milepost 0 to 130.
When conditions warrant, signs along the roadway will notify drivers that their vehicles’ tires must be chained or have approved alternate traction devices. CMVs required to chain four drive tires include:
- Straight trucks,
- Single drive axle combinations,
- Tandem drive axle combinations, and
- Auto transporters.
Fines
The minimum fines for non-compliance are:
- $50 for not carrying tire chains or alternate traction devices as required,
- $500 for not chaining up when signs along the roadway indicate when the chain law is in effect and that vehicles must be chained, and
- $1,000 for blocking the roadway as a result of not chaining up.
Key to remember: Drivers operating on Colorado highways need to be aware of the state’s tire chain laws, including the expanded “must carry” requirements.
