Every winter, Colorado truck citations on I-70 increase due to drivers failing to follow the chain law. The I-70 chain law is mandatory for all commercial vehicles traveling through mountain passes between Milepost 133 (Dotsero) and Milepost 259 (Morrison). This regulation requires truckers to use tire chains when snow, ice, or adverse conditions exist. Failing to comply can result in hefty fines ranging from $500 to $1,000 and even vehicle impoundment in severe cases. The purpose of the law is to ensure safety and maintain traffic flow during winter storms. Truck drivers must always carry chains between September 1 and May 31, as weather conditions can change rapidly. Staying compliant not only prevents citations but also protects lives and reduces road closures.
