Colorado expands chain law just in time for winter driving chaos

In the United States, particularly in Colorado, a noteworthy change occurred to improve safety measures for winter driving conditions. The state's mandatory chain law has been expanded to cover a wider geographical area impacting commercial motor vehicles. This new regulation went into effect starting in September 2024, ahead of the winter season. The law specifically targets areas prone to challenging weather, as Colorado has seen significant difficulties with traffic disruptions and road closures, especially along the I-70 mountain corridor. This corridor is uniquely important, as it is the only east-west interstate in the state and serves as a crucial transportation route for commerce. The Colorado State Patrol (CSP) and Colorado Department of Transportation (CDOT) have been at the forefront of implementing these changes to minimize risks associated with driving through steep inclines and treacherous weather conditions. Prior to these regulations, the state experienced extended closures due to weather-related incidents, leading to public safety concerns and economic impacts. With the new laws in place, commercial motor vehicles must be equipped with chains from September 1 to May 31, particularly affecting areas like I-70 from Dotsero to Morrison, as well as numerous state and federal highways west of I-25. Furthermore, this legislation restricts these vehicles from using left lanes in certain areas known for steep grades and curves, aiming to enhance traffic flow and reduce the likelihood of accidents. This change reflects a proactive approach by state lawmakers to encourage safer driving practices and ensure that essential goods and services can continue to be transported effectively despite adverse weather. By enforcing these measures, Colorado aims to create a safer environment for all motorists during the winter months and reduce the economic strain caused by weather-related disruptions.
