From Sept. 1 through May 31, all commercial vehicles traveling on I-70 between the Edwards exit (mile point 133) and the Morrison exit (mile point 259) must carry enough chains to be in compliance with the Colorado chain law.

Chains help commercial vehicles traverse the steep climbs often present in the high country.  Without chains, vehicles often become disabled, causing traffic delays and sometimes road closures. For the safety of the traveling public, it’s critical to use chains to be in compliance with Colorado’s chain law.

Colorado’s chain law applies to all state, federal and interstate highways, and was initially enacted in 1996. Colorado’s chain law defines commercial vehicles as being used in commerce to transport passengers or property and fitting into one of the following categories:

  • Gross combination weight rating of 26,001 or more pounds, inclusive of a towed unit, which has a gross vehicle weight-ratio of more than 10,000 pounds
  • Gross vehicle weight rating of 26,001 or more pounds
  • Designed to transport 16 or more passengers, including the driver

Colorado has a Truck Parking Guide with a map that shows you chain up locations, parking, exits, and rest stops for I-70, I-25, and I-76.    Clicking on the following link you will find helpful hints for crossing the Rockies. 

With, Star Fleet’s winter driving policies are to be followed when road and weather conditions are hazardous.  If you must put chains on you shouldn’t be on the road.  Our Customers will not allow us to put chains on the RVs.  In the upcoming fall and winter months it is extra important to pre-plan and have plans for adverse weather conditions. Remember more states will soon be following with their chain laws.  Check out the chain law app from OOIDA to help you keep up on chain laws for all states and its free.
