As winter weather returns to Colorado’s high country, drivers are being reminded that the state’s updated Chain and Traction Laws apply to all vehicles — not just big trucks.
From September through May, all commercial vehicles over 16,000 pounds must carry chains on key routes, including sections of I-70, U.S. 550, and U.S. 160. When the Commercial Vehicle Chain Law is in effect, those larger vehicles must chain or use approved traction devices on up to four drive tires.
For smaller passenger vehicles, the Traction Law can go into effect anytime conditions warrant. Two-wheel drive cars must have tires rated for mud and snow or all-weather use with at least three-sixteenths of an inch of tread — or they must use chains or alternate traction devices. Four-wheel and all-wheel drive vehicles must engage all drive wheels and meet the same tread standards.
When the Passenger Vehicle Chain Law is activated, all cars — regardless of drivetrain — must have chains or traction devices on at least two drive tires.
Fines for violating winter driving restrictions can reach up to a thousand dollars if you block traffic.
