Denver, CO – Colorado State Patrol is reminding commercial drivers that the state’s chain law is now in effect as of today, requiring tire chains on commercial motor vehicles from Sept. 1 through May 31.
According to Colorado State Patrol, the law is designed to keep highways safe during snow season, particularly on mountain passes where weather conditions can quickly change. Trucks without chains face the risk of losing traction, causing road closures and significant safety hazards for other drivers.
Officials said chain requirements apply to all commercial vehicles traveling on Interstate 70 between Morrison and Dotsero during severe winter weather, but the statewide rule requires drivers to carry chains throughout the season. Fines for not complying with the law can reach up to $650, and if a vehicle without chains blocks traffic, penalties can climb to $1,500.
The patrol urged truckers and other commercial drivers to plan ahead, noting that snow “doesn’t take excuses, so neither should you.” Drivers are encouraged to check road conditions before traveling by visiting COTrip.org, the state’s official travel information site.
Colorado has some of the steepest and most heavily traveled mountain highways in the nation, and transportation officials said keeping chains ready is not only a matter of compliance but also critical for safety during unpredictable fall, winter, and spring storms.
