The Colorado State Patrol has released a review of its winter chain law enforcement along Interstate 70, highlighting the challenges faced during a particularly harsh season. Officials focused on ensuring commercial vehicles complied with state requirements to carry and use chains, aiming to improve safety along this critical mountain corridor.
Winter Enforcement Operations
From February through the end of the season, the Colorado State Patrol conducted 13 weekly surge operations along I-70, working with local police departments and sheriff’s offices. State Patrol Motor Carrier Safety Captain John Hahn reported that of 1,836 commercial vehicles checked during these operations, 109 citations were issued for failing to carry chains, representing about 6% of the vehicles stopped. These statistics illustrate ongoing enforcement challenges along one of Colorado’s busiest mountain highways.
The enforcement wasn’t limited to commercial trucks. Officers contacted 760 passenger vehicles, issuing 399 speeding citations, or roughly 52% of those checked. Hahn emphasized the shared responsibility for safe driving along I-70, noting that passenger vehicles often create hazards by cutting off trucks or following too closely.

Chain Law Violations and Fines
Outside of weekly operations, chain law compliance was also enforced at ports of entry, chain-up stations, and during routine roadside stops. At the Dumont port of entry alone, 1,382 citations were issued to commercial vehicles failing to carry chains, a 30% increase from the previous year.
Commercial drivers face strict penalties under Colorado law:
-
$133 for failing to carry chains between September 1 and May 31
-
$579 for failing to install chains when chain law is active
-
$1,157 for blocking a lane due to failure to chain up
Hahn acknowledged that the 2024-2025 winter was particularly challenging, with adverse weather contributing to road closures and incidents. He stressed that enforcement and driver responsibility remain key to preventing accidents and maintaining traffic flow.
Impact on Interstate Commerce
The I-70 corridor is crucial for both regional and national commerce. Greg Fulton, president of the Colorado Motor Carriers Association, noted that traffic has increased 30% over the past two decades, creating heightened risks when trucks encounter snow and ice. Commercial trucks are essential for supplying goods to communities on the Western Slope, and drivers often travel in hazardous conditions out of necessity.
Fulton emphasized that compliance with chain laws, along with additional support like rest areas and chain-up sites, is essential to prevent extended closures and maintain the flow of goods.
Legislative Actions and Future Plans
To improve safety and compliance, the Colorado legislature recently passed Senate Bill 69, allowing third-party vendors to help commercial drivers install chains along I-70 and other mountain roads. This bill also introduces tighter tire tread requirements for four-wheel-drive vehicles and mandates rental companies inform customers about chain law and penalties.
Hahn explained that while fines and enforcement are important, supporting drivers with chain-assist programs can reduce incidents and get trucks moving faster during winter storms. The goal is to reduce both accidents and extended road closures that can disrupt commuters and commercial traffic alike.
Local Measures and Fines
Some municipalities, such as Vail, have enacted stricter fines for chain law violations, with penalties up to $2,650 for incidents blocking a road. Local law enforcement leaders, including Vail Police Chief Ryan Kenney, emphasized that the intention is not to penalize truckers unfairly but to ensure safety for all motorists.
Sen. Dylan Roberts, a sponsor of SB 69, stated that increasing fines alone isn’t a complete solution. Combining enforcement with infrastructure support, driver education, and assistance programs is necessary to prevent accidents and maintain safe travel on the I-70 corridor.
