Before Every Winter Trip

Check conditions first, then decide whether the trip should happen.

Colorado mountain weather and road conditions can change during a single drive. Before leaving, review the National Weather Service forecast and use COtrip for current state-highway conditions, cameras, incidents, closures, and active traction or chain restrictions.

Plan extra time, reduce speed for the conditions, increase following distance, and avoid sudden steering or braking. When conditions are severe, postponing a trip may be the safest decision.

A familiar road can become a different road when snow, wind, shade, and freezing temperatures arrive.

Vehicle Readiness

Prepare the vehicle before the storm.

Colorado Department of Transportation guidance emphasizes winter-appropriate tires, adequate tread, current travel information, and emergency supplies. Vehicle capability does not replace careful driving.

01 · TIRES

Use compliant tires

Know the current Colorado traction-law requirements and confirm that your tires, tread depth, drivetrain, or approved traction devices meet the rule when it is activated.

02 · VISIBILITY

Clear the entire vehicle

Remove snow and ice from windows, mirrors, lights, roof, hood, and license plates. Maintain working wipers and winter-rated windshield fluid.

03 · POWER

Check battery and fuel

Cold weather can expose a weak battery. Keep enough fuel or charge for delays, detours, and time spent waiting safely.

04 · EMERGENCY KIT

Carry essential supplies

Include warm clothing, blankets, water, food, flashlight, phone charger, basic first aid, ice scraper, and traction aids suitable for your vehicle.

05 · COMMUNICATION

Share your plan

Tell someone your route and expected arrival time when traveling during a storm or through less-populated areas where cellular service may be limited.

06 · DECISION

Know when to wait

Warnings, closures, poor visibility, rapidly accumulating snow, or an unprepared vehicle are valid reasons to delay travel.

Colorado Traction Laws

Traction and chain requirements can be activated on state highways.

CDOT may activate the Passenger Vehicle Traction Law on any state highway. Current requirements depend on tire type, tread depth, drivetrain, or the use of chains or another approved traction device. During the more restrictive Passenger Vehicle Chain Law, every passenger vehicle must use chains or an approved alternative traction device.

Requirements can change, and enforcement details matter. Review CDOT's current traction-law page before winter travel rather than relying on an old summary or assumption about four-wheel drive.

Road Ownership Matters

State highways, county roads, town streets, and private roads are maintained differently.

Knowing who maintains a road helps you find accurate closure information, snow-removal policies, and service contacts.

01 · STATE HIGHWAYS

Use COtrip

U.S. Highways 34 and 36 are state highways. COtrip is the official source for CDOT road conditions, cameras, incidents, closures, and traction-law information.

02 · COUNTY ROADS

Check Larimer County

Larimer County maintains designated county roads under its snow-and-ice policy. Priorities vary, and county crews do not clear private driveways.

03 · TOWN STREETS

Review Town information

Roads inside town limits may be maintained by the Town of Estes Park. Confirm snow-removal rules, parking restrictions, and current local notices through the town.

04 · PRIVATE ROADS

Verify the agreement

Some mountain properties use private roads or shared driveways. Ask who plows, who pays, what standard is expected, and whether a written maintenance agreement exists.

05 · DRIVEWAYS

Plan for grade and access

Steep, shaded, narrow, or north-facing driveways may retain snow and ice. Evaluate winter access, turnaround space, drainage, and the equipment needed for maintenance.

06 · PARK ROADS

Check Rocky Mountain National Park

Trail Ridge Road is seasonal and closes to through travel in winter. Conditions and opening dates are weather dependent, so use the National Park Service road-status page before entering the park.

Before Buying a Mountain Property

Winter access is a property-specific question.

Ask who maintains the road and driveway, whether snow removal is included in an association or road agreement, where snow can be stored, and whether delivery trucks and emergency vehicles can reach the home during winter.

Visit the property after snow if possible. A summer showing may not reveal shaded ice, plow berms, drainage problems, steep grades, limited turnarounds, or the practical effort required to keep access open.
