There are times when Colorado requires chains on commercial vehicles (State of Colorado photo)It’s that time of year again when commercial motor vehicles on part of one interstate must carry tire chains and be ready to use them in case of bad weather.
State law requires that between Sept. 1 and May 31 all commercial vehicles traveling on I-70 between milepost 133 (Edwards exit) and milepost 259 (Morrison exit) must be in compliance with the Colorado chain law.
According to the state, its 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 lbs. inclusive of a towed unit which has a gross vehicle weight ration of more than 10,000 lbs.
- Gross vehicle weight rating of 26,001 or more lbs.
- Designed to transport 16 or more passengers, including the driver
