Truckers Face Fines Ranging from $579 to $1,157 for Chain Law Violations
The Colorado State Patrol (CSP) has launched a strict enforcement effort targeting truckers who fail to follow the state’s updated chain laws. Officers are now conducting random inspections and issuing hefty fines to any commercial vehicle that isn’t carrying tire chains. These measures, which began on February 27, aim to prevent accidents and traffic standstills that have plagued Interstate 70 (I-70) in previous winters.
This year, troopers are stopping trucks even on clear roads to confirm compliance. Drivers who fail to carry chains will receive a $500 fine, plus a $79 surcharge. Those who block traffic because of inadequate traction face an even steeper penalty: $1,000, plus a $157 surcharge.
Colorado has endured countless highway shutdowns due to unprepared truckers. As a result, state officials have tightened restrictions, emphasizing safety and efficiency on critical mountain routes.
Colorado’s Expanded Chain Law: What’s Changed?
Previously, truckers only needed tire chains along a 129-mile stretch of I-70 between Dotsero and Morrison. However, the revised law, which took effect in August 2024, now applies to multiple highways across the state.
Commercial truck drivers must carry tire chains from September 1 to May 31 when traveling on these routes:
- I-70 (Morrison to the Utah border)
- U.S. Route 40 (Empire to the Utah border)
- U.S. Route 50 (Salida to the Utah border)
- U.S. Route 160 (Walsenburg to the New Mexico border)
- U.S. Route 285 (Morrison to the New Mexico border)
- U.S. Route 550 (entire route)
- Colorado State Highway 9 (Frisco to Fairplay)
Additionally, all commercial vehicles over 16,000 pounds must have chains or alternative traction devices on at least four drive tires during this period. Passenger vehicles must have 3/16-inch tread depth tires rated as “all-weather” or “mud and snow.”
State officials expanded this law in response to previous winter traffic catastrophes, where jackknifed trucks frequently blocked highways, forcing detours, delaying freight, and stranding emergency vehicles.

Why Is Colorado Cracking Down?
Colorado authorities have seen enough traffic disasters caused by ill-prepared truckers. The Rocky Mountain corridor remains one of the most treacherous stretches of highway in the U.S., with rapidly changing weather, steep inclines, and frequent ice hazards.
Each winter, unprepared truckers get stuck, causing miles of backups. These incidents don’t just delay freight—they also:
- Trap thousands of drivers in freezing conditions for hours.
- Disrupt supply chains by delaying essential shipments.
- Divert emergency responders who should be assisting elsewhere.
According to Summit Daily News, the chain law isn’t just about fines—it’s about ensuring that roads remain open and passable for everyone.
Officials have little patience left for repeat offenders, and enforcement efforts have intensified to minimize avoidable highway closures.
How Are Troopers Enforcing the Law?
This winter, Colorado State Patrol has stepped up enforcement measures. Officers now conduct proactive chain checks, stopping trucks even when the pavement remains dry.
“The problem isn’t just when it’s snowing,” a CSP officer told CBS News Colorado. “It’s about making sure truckers are always prepared. When a storm hits, we can’t afford to have unprepared drivers clogging up the mountain passes”.
What Truckers Can Expect This Winter:
- Increased roadside inspections, even in clear weather.
- Expanded chain enforcement at mountain passes and chain-up stations.
- Zero tolerance for truckers attempting to bypass chain-up areas.
Troopers remain firm on their stance: If your truck isn’t equipped with chains, expect a ticket.
New Left-Lane Restrictions for Truckers
Colorado’s updated traffic laws don’t stop at chain requirements. The state has also tightened left-lane restrictions for commercial vehicles, further limiting movement on I-70.
Large trucks must stay out of the left lane in the following areas:
- Glenwood Canyon
- Dowd Junction (Avon to Vail)
- Vail Pass (west side)
- Eisenhower-Johnson Tunnel (both sides)
- Georgetown Hill & Floyd Hill
With fewer trucks in the left lane, state officials hope to reduce unnecessary slowdowns and improve overall traffic flow.
Troopers are actively enforcing these restrictions, and violators will receive additional fines on top of chain law penalties.
The Cost of Ignoring Colorado’s Chain Law
Truckers who think they can avoid carrying chains may find themselves facing costly fines:
- $500 fine plus a $79 surcharge for failing to carry chains when required.
- $1,000 fine plus a $157 surcharge for getting stuck and blocking traffic.
Ignoring these regulations can quickly add up, especially for fleet operators managing multiple drivers.
“Carrying chains is a basic requirement for winter driving,” a Vail Daily spokesperson noted. “Truckers who ignore this law aren’t just putting themselves in danger—they’re creating risks for thousands of other drivers”.
The Takeaway: Be Prepared or Be Ready to Pay
Colorado’s strict new enforcement measures remain in effect throughout the winter season.
Truckers traveling through the Rockies must prepare for changing weather conditions and comply with all chain laws to avoid costly fines.
What Every Trucker Must Do to Stay Compliant:
Carry DOT-approved tire chains at all times during the mandated period.
Ensure chains fit and are in good condition before hitting the road.
Pay attention to road signage and chain-up station requirements.
Obey all lane restrictions and avoid using the left lane in restricted areas.
Authorities aren’t making exceptions this year. Troopers will continue conducting strict roadside inspections, and drivers who ignore the law will face immediate penalties.
Final Warning: Chain Up or Pay Up!
Truckers traveling through Colorado this winter must take these requirements seriously.
Troopers are monitoring compliance. Fines are substantial. Unprepared drivers will be held accountable.
Carrying tire chains isn’t optional—it’s the law.
