Colorado winter driving brings heightened risks, especially along northern Front Range corridors and mountain highways. As a Fort Collins Car Accident Lawyer team, Cannon Law regularly helps injured drivers sort through liability questions tied to winter crashes. Many clients ask what is traction law in Colorado, and how violations affect accident claims. In simple terms, Colorado updated the Passenger Vehicle Traction Law to raise safety standards during winter weather. State transportation officials now require qualifying tires with at least 3/16-inch tread depth, including winter tires marked with the mountain snowflake symbol, all-weather rated tires, or mud and snow tires, according to Colorado transportation guidance. This change strengthens roadway safety during storms and plays a critical role after a collision involving loss of control.
CALL US (970) 471-7170When the Colorado Traction Law Goes Into Effect
The Colorado Department of Transportation (CDOT) activates the Passenger Vehicle Traction Law during winter storms or whenever road conditions require extra vehicle control. CDOT holds the authority to trigger the Traction Law, Passenger Vehicle Chain Law, or Commercial Vehicle Chain Law on any state highway across Colorado, responding to real-time weather developments and safety concerns.
Each year, the Traction Law automatically takes effect from September 1 through May 31 along the I-70 Mountain Corridor between Dotsero and Morrison. This stretch experiences some of Colorado’s most severe and unpredictable winter conditions. CDOT may also activate the law on other highways when snow, ice, or poor visibility creates hazardous conditions that threaten driver safety.
The regulation applies to all non-commercial drivers, with penalties for noncompliance set at a $50 fine plus a $17 surcharge. Law enforcement actively monitors compliance during activations.
Traction Requirements Every Colorado Driver Must Follow
Once CDOT activates the Traction Law, drivers must equip their vehicles to meet specific standards designed to maintain control on snowy or icy roadways.
AWD or 4WD vehicles must have one of the following:
- Mud-and-snow tires (M+S icon) with at least 3/16-inch tread depth
- Winter tires (mountain-snowflake icon) with at least 3/16-inch tread depth
- Manufacturer-rated all-weather tires with at least 3/16-inch tread depth
Any vehicle can comply by using:
- Chains or an approved alternative traction device, properly installed
CDOT designed these standards to prevent spinouts, jackknifing, and multi-vehicle collisions during winter storms. Tread depth matters; worn tires lose their ability to channel snow and water, compromising traction even on AWD systems. The 3/16-inch minimum ensures grooves remain deep enough to grip slick pavement effectively. Compliance depends on both your vehicle’s drivetrain and tire condition. Two-wheel-drive vehicles without chains do not meet the legal standard and risk citation during enforcement.
Understanding what is traction law in Colorado requires recognizing how tire condition and drivetrain choice directly influence legal compliance.
What Happens If You Drive Without Proper Traction Equipment
Driving without compliant traction equipment during an active Traction Law period exposes motorists to more than a fine. Vehicles lacking required tires or devices often lose control on icy grades, block lanes, or trigger chain-reaction crashes. Law enforcement may issue citations, and towing costs usually follow when a disabled vehicle obstructs traffic. Beyond immediate penalties, documentation of noncompliance frequently appears in crash reports. Insurance carriers review those details closely during claim evaluations, especially when winter road conditions contribute to loss of control. Drivers unfamiliar with what is traction law in Colorado often underestimate how quickly a simple equipment oversight escalates into financial and legal consequences.
How Traction Law Violations Can Affect a Car Accident Claim
A traction law violation can support a negligence argument in a Colorado car accident case. When a driver ignores active traction requirements and causes a crash, insurers and defense attorneys often argue that failure to use required equipment contributed to the collision. Colorado follows a modified comparative negligence framework, which means fault allocation matters. Evidence such as tire tread measurements, photographs of sidewalls, or citations issued at the scene may reduce recoverable damages for a noncompliant driver. Conversely, injured motorists struck by a vehicle lacking proper traction equipment may strengthen liability arguments. Winter crash investigations often hinge on whether drivers met state-mandated safety standards during storm conditions.
