Planning a ski trip to the Colorado mountains this winter? Colorado’s traction law isn’t just a suggestion; it’s a legal requirement that could save your life. The law mandates specific tire equipment based on road conditions: winter tires with the mountain/snowflake symbol, adequate all-wheel drive with proper tread depth, or tire chains when conditions deteriorate. At Autovisions in Englewood, CO, we help families understand what these symbols mean, when chains become non-negotiable, and why your all-season tires might not be enough.
This guide walks you through the traction law requirements, reveals the truth about four-wheel drive, shows you how to time your winter tire installation perfectly, and explains what equipment keeps you legal on I-70’s notorious mountain corridor.
Breaking Down Colorado's Traction Law Requirements
During a Traction Law, your vehicle must meet specific criteria based on your drivetrain configuration and tire setup. Here’s what you need to know:
For Four-Wheel or All-Wheel Drive Vehicles:
- Tires with M+S (Mud and Snow) designation and 3/16-inch minimum tread depth
- Winter tires displaying the mountain/snowflake symbol with 3/16-inch tread depth
- All-weather rated tires by the manufacturer with 3/16-inch tread depth
For Two-Wheel Drive Vehicles:
- Winter tires with the mountain/snowflake symbol and adequate tread depth
- Tire chains or approved alternative traction devices are properly installed
The mountain/snowflake symbol matters because it’s the only marking that proves your tire meets severe snow service standards. Regular all-season tires don’t cut it when the traction law activates. For detailed requirements and current road conditions, visit CDOT’s traction law page.
The Hidden Cost of Ignoring Traction Requirements
Beyond fines and citations, unprepared vehicles create dangerous situations that affect everyone on the road. When drivers proceed without proper equipment, they risk spinning out, blocking traffic, and creating chain-reaction accidents that close highways for hours.
Insurance companies also look at traffic law compliance when processing winter accident claims. If you’re involved in a collision and your tires didn’t meet legal requirements, it impacts fault determination and coverage.
When Chain Law Takes It to the Next Level
The Passenger Vehicle Chain Law is the final safety measure before CDOT closes highways completely. When this activates, everyone needs chains or approved alternative traction devices installed, including four-wheel and all-wheel drive vehicles.
Chain Installation Basics:
- Front-wheel drive: chains on front tires
- Rear-wheel drive: chains on rear tires
- All-wheel drive: chains on all four wheels recommended
Approved alternative traction devices include AutoSock from McGee Company and EasySox from Quality Chain Corporation. These fabric-style devices install more easily than traditional chains, though they cost more upfront.
Keep chains accessible in your vehicle from September through May if you drive mountain roads regularly. Having them buried in your garage doesn’t help when you’re turned around at a checkpoint.
Why Winter Tires Beat All-Season in Colorado
Winter tires dramatically outperform all-season tires in snowy conditions, requiring significantly less distance to stop. The performance difference becomes critical when you need to brake quickly on mountain passes or slippery metro streets.
Winter tires use specialized rubber compounds that stay flexible when temperatures drop below 45°F. All-season tires harden in cold weather, losing grip even on dry pavement. The deeper tread patterns and thousands of tiny cuts called sipes help winter tires bite into snow and ice while channeling away slush and water.
The Four-Wheel Drive Myth
Four-wheel drive helps you accelerate and maintain momentum in slippery conditions, but does nothing for stopping distance or cornering grip. You still need proper tires to brake effectively and maintain control through turns.
Essential Pre-Winter Vehicle Checks
Getting your vehicle ready for Colorado winter goes beyond tires. These systems need attention before temperatures drop:
Fluid Check Priority List:
- Engine Oil: Consider full synthetic for better cold-weather flow
- Coolant: Test concentration to prevent freezing
- Brake Fluid: Check for moisture contamination
- Windshield Washer Fluid: Switch to winter formula
Battery and Electrical:
- Test battery capacity since cold reduces cranking amps by 30-50%
- Clean corrosion from terminals
- Inspect battery age, replacing anything over 4 years old
Brake and Suspension:
- Measure brake pad thickness and rotor condition
- Inspect suspension components for wear
- Verify that shock absorbers control bounce properly
Timing Your Winter Tire Installation
October marks the sweet spot for installing winter tires in the Denver metro area. Wait too long and you’re scrambling for appointments when the first major storm hits. Install too early in warm weather and you’ll wear down the softer rubber compound unnecessarily.
Many smart drivers maintain a dedicated set of winter wheels and tires, making seasonal swaps faster and protecting their regular tires from road salt and harsh conditions.
The October Rush is Real
Once temperatures consistently stay below 45°F at night, everyone suddenly remembers they need winter tires. Shops get slammed, wait times stretch to weeks, and popular sizes sell out. Booking your appointment in early October beats the chaos.
Real-World Mountain Driving Beyond Tire Laws
Understanding legal requirements only covers part of winter driving preparation. Check CDOT’s winter driving resources before heading to the mountains for real-time updates on road conditions.
Before You Leave:
- Check COtrip.org or the mobile app for current conditions
- Monitor weather forecasts for your entire route
- Allow 50% more travel time than summer conditions
- Consider delaying trips when major storms approach
Emergency Kit Essentials:
- Warm blankets and extra winter clothing
- Flashlight with fresh batteries
- First-aid supplies and critical medications
- Non-perishable snacks and bottled water
- Ice scraper, small shovel, and traction mats
- Fully charged phone and external battery pack
Keep your gas tank above half-full during the winter months to prevent fuel line freeze-ups and provide reserves if you’re delayed.
How Englewood Drivers Prepare Differently
In Englewood, Colorado, it’s easy to enjoy quick weekend trips to the mountains, whether you’re heading to Breckenridge, Keystone, or Loveland Pass. But with those short drives comes a big change in elevation and weather, which can catch drivers off guard if their vehicles aren’t properly prepped for winter. The elevation change from Englewood to popular ski areas drops temperatures 15-20°F and dramatically changes road conditions.
The Tire Pressure Temperature Effect
For every 10°F temperature drop, your tires lose approximately 1 PSI of pressure. When you drive from 60°F Englewood to 25°F mountain conditions, you’ve lost 3-4 PSI. Underinflated tires reduce traction and increase stopping distance. Checking pressure weekly during fall and winter prevents these problems.

FAQs About Colorado's Traction Law and Winter Driving
What maintenance should I do on my car in the fall?
Fall maintenance should prioritize fluid checks, battery testing, tire inspection for tread depth and pressure, and brake system evaluation. These services prepare your vehicle for temperature changes and winter conditions that stress every system.
How do I prepare my car for cold weather?
To prepare your car for cold weather, check the coolant, test the battery, inspect the tires, and make sure the heater and defroster work properly. These steps help prevent breakdowns and ensure safe driving in freezing temperatures. Even mild cold can reduce battery power and tire pressure, making winter prep essential for reliability and safety.
What fluids should be checked before winter?
Check engine oil, coolant/antifreeze mixture, brake fluid for moisture, transmission fluid, power steering fluid, and winter-rated windshield washer fluid. Each fluid plays a critical role in cold-weather operation and should meet manufacturer specifications.
How often should I replace winter tires?
Winter tires typically last three to four seasons of regular winter use, depending on driving habits and mileage. Once tread depth reaches 5/32 inch or the rubber shows signs of hardening and cracking, replacement maintains safety and performance.
Do I need winter tires if I have all-wheel drive?
All-wheel drive helps with acceleration and maintaining momentum in slippery conditions, but doesn’t improve stopping distance or cornering grip. Winter tires provide superior traction for braking and handling regardless of your vehicle’s drivetrain configuration, making them valuable for any vehicle.
