How to Prepare for Snow and Ice While Driving in Colorado

Winter in Colorado is no joke. Here’s how to prepare for snow and ice before hitting the road.

1. Know the Laws

Two main rules:

Traction Law (Code 15):
- AWD/4WD
- OR 3PMSF tires
- OR chains
- Tread depth ≥ 3/16"

Passenger Chain Law (Code 16):
- Chains or AutoSocks required for ALL vehicles during major storms

Check current status at cotrip.org

2. Get Real Snow Tires

All-season isn’t enough. Use:
- Tires with 3PMSF symbol
- At least 4/32" tread
- Check tire pressure — it drops in cold

AWD won’t help if your tires can’t grip.

3. Build a Winter Kit

Pack:
- Ice scraper + snow brush
- Shovel
- Sand or litter
- Blanket
- Gloves, hat, socks
- Flashlight
- Snacks, water
- Phone charger
- Jumper cables

4. Change How You Drive

- Brake early and soft
- Don’t accelerate fast
- Leave big following distance
- Downshift on hills
- Use low beams (not brights) in snow

5. Clear Your Car

Fully clear:
- Roof
- Windows
- Headlights
- Taillights
- License plate

You CAN get ticketed for poor visibility.

6. Turn Around If It Gets Bad

Red flags:
- Near-zero visibility
- CDOT announces closures
- You see cars sliding

Park somewhere safe and wait it out.

7. Check Conditions Before You Go

Visit:
- cotrip.org (live cams + alerts)
- Twitter: @ColoradoDOT
- Weather apps with radar + snow totals

8. Watch for Black Ice

Where?
- Bridges
- Shady corners
- Sunrise or dusk hours

If you slide:
- No brakes!
- Ease off gas
- Steer gently

9. Pick the Right Car

Best:
- AWD/4WD + snow tires
- SUV or high-clearance vehicle

Avoid:
- Rear-wheel sedans
- Bald tires
- Low-clearance rentals

10. Final Tip

Prepare like your trip depends on it — because it does. Slow down, stay alert, and don’t be afraid to call it off. The mountain will still be there tomorrow.
