Denver, Colo. — Colorado State Patrol announced that more than 2,700 citations have been handed out for violations of the state’s mandatory chain‑carry law during the current enforcement period.

The chain‑carry rule forces commercial trucks to equip and use tire chains when traveling through designated mountain corridors during winter weather. Non‑compliance can lead to loss of traction, accidents, and costly road closures—issues that weigh heavily on owner‑operators and fleet managers alike. With the chain‑carry season set to close on May 31, the patrol’s aggressive approach aims to keep the interstate clear and safe for the heavy traffic that moves OTR freight across the Rockies.

Patrol officials reported that port‑of‑entry officers performed weekly proactive inspections at every major entry point, issuing 2,218 citations on the spot. Mobile checkpoint teams cruising the I‑70 corridor added 187 citations during their monthly sweeps, while 317 “port runner” stops caught drivers who tried to evade the inspection stations only to be flagged later by troopers. The data also shows that 9.6% of drivers pulled over in the mobile operations failed to meet the Must‑Carry requirement, a figure that underscores lingering gaps in compliance.

What This Means for Drivers

CDL‑A holders hauling loads through Colorado’s mountain passes must keep chains on hand and ready to install at any moment, or risk a hefty fine and possible delay. Owner‑operators should inventory their chain kits before the season starts and verify that each set meets FMCSA specifications to avoid the 9.6% violation rate that could trigger a citation. Fleet managers need to schedule chain‑installation drills for drivers, ensuring that the process can be completed in minutes to keep schedules on track and prevent costly downtime. The heightened patrol presence also means that any attempt to bypass a port‑of‑entry checkpoint will likely result in a “port runner” stop and an additional citation.

Industry Reaction

Trucking associations have long warned that inconsistent enforcement creates uncertainty for carriers operating in the region. While the Colorado State Patrol’s numbers demonstrate a crackdown, many drivers appreciate the clarity that comes from a uniform, well‑publicized enforcement campaign. Some owner‑operators argue that the 9.6% non‑compliance figure reflects a need for better education on chain‑carry obligations rather than harsher penalties. Overall, the industry views the data as a reminder that winter preparedness remains a critical component of safe, on‑time freight movement.
