Colorado could make winter tires, AWD, or chains mandatory on Interstate 70

Motorists traveling through Colorado could face penalties this fall for traveling a section of Interstate 70 in winter without all-wheel drive, winter tires, or snow chains.

The Colorado Sun reported Monday that a bill in the state would require drivers to have prepared for winter weather to travel on I-70 between Morrison and Glenwood Springs, a roughly 150-mile stretch of mountainous road. The bill would require drivers be prepared for winter’s worst weather between September and May, sunshine or snowfall.
