How to handle Traction Law Alert when driving I-70 through Colorado mountains in a rented AWD?

Just found answers to questions 1 and 2:

Traction Law (Code 15)

During an active Traction Law (also known as a Code 15), motorists must have either snow tires, tires with the mud/snow (M+S) designation, or a four-wheel/all-wheel drive vehicle. All tires must have a minimum one-eighth inch tread.

Under a Traction Law, both metal-studded and studless snow tires comply with the "snow tire" requirement of the law. CDOT recommends using studless snow tires instead of studded because studded tires can chip and cut grooves in the road, creating a hydroplaning hazard when the roadway is wet. Whether using studded or studless snow tires, all the tires must have a minimum one-eighth inch tread.

So, if it was the Traction Law alert only (not Chain Law Alert) then an AWD would be fine even with non-winter tires. But there was also a Chain Law Alert which requires ALL vehicles to have chains fitted:

Under an active Passenger Vehicle Chain Law, every passenger vehicle will need to have chains or an alternative traction device equipped.
