The Passenger Vehicle Traction Law is active. Your AWD passenger vehicle relies on its tires instead of chains. Which tire condition is required?
Correct answer: Winter, mud-and-snow or all-weather tires with at least 3/16-inch tread.
Why
Current CDOT guidance requires an AWD or 4WD passenger vehicle using the tire option to have winter, mud-and-snow or manufacturer-rated all-weather tires with at least 3/16-inch tread. Otherwise use the required chains or approved alternative traction devices. Check posted restrictions before traveling; AWD does not shorten your stopping distance on ice.
