Winter Driving Intelligence
Assess Snow & Ice Conditions from Your Driveway
VIEW WINTER CAMERAS →Winter driving causes approximately 116,800 injuries and over 1,300 fatalities annually in the U.S. according to the Federal Highway Administration (FHWA). Icy road conditions are particularly lethal, accounting for 3.6 times more deaths than all other weather hazards combined. The difference between a safe commute and a dangerous journey often comes down to real-time information. While weather apps predict what might fall, traffic cameras show what is actually sticking to the road. This guide teaches you to professionally assess pavement conditions through live visual data.

Winter conditions contribute to approximately 24% of all weather-related vehicle crashes, making visual confirmation of road status a critical safety buffer.
For a data-driven look at how weather conditions affect traffic patterns year-round, see our weather impact analysis guide.
Sticking vs. Falling: A forecast for "light snow" tells you nothing about the pavement temperature. Cameras reveal ground truth: Is the snow compacting into ice? Has treatment prevented bonding? Are lane lines still visible?
Visualizing Road Treatment
Traffic cameras provide direct visibility into the effectiveness of highway maintenance. The integration of technology and monitoring has proven results; for example, the use of variable speed limit (VSL) signs linked to real-time monitoring in Pennsylvania led to a 34% reduction in serious injuries and fatalities during winter events.
According to the FHWA, real-time traffic monitoring helps drivers make safer, more informed decisions. Research also shows that automated speed enforcement programs can reduce crashes by up to 39%, providing an extra layer of deterrence against reckless driving during hazardous winter conditions.
Assessing Snow Accumulation
- Trace Snow (<1"): Pavement visible between wheel tracks; lane markings discernible. Caution on bridges.
- Moderate (1-3"): Lane markings obscured; visible tire spray indicates slush. Spacing increases to 4-5 seconds.
- Heavy (3-6"): Little to no pavement visible; traffic slows to 30% of normal speeds. 4WD/Winter tires strongly recommended.
- Severe (6+"): Pavement invisible; vehicles struggling to maintain progress. Extreme risk of being stranded.
Check Mountain Pass Conditions
Monitor high-elevation summits for whiteout conditions and chain requirements in real-time.
VIEW PASS CAMERAS →Advanced Ice Detection
Ice is nearly invisible, making it the most dangerous winter hazard. Use these camera-based interpretation techniques:
Black Ice Cues
- The Glossy Look: Pavement looks "wet" but temperatures are below 32°F.
- Following Distance: Traffic maintaining 6+ seconds of spacing on apparently clear roads.
- No Spray: If roads look wet but vehicles are producing zero splash/spray, the moisture is frozen.
Bridge Warning
Bridges and overpasses lose heat from both above and below, freezing up to 10°F earlier than ground-level roads. Always compare bridge deck appearance to the approaching roadway in the same camera frame.
Time-of-Day Hazards
Morning Freeze
Dawn to 9:00 AM
Overnight refreezing of daytime melt. Look for "hardpack" where traffic has compressed snow into smooth ice.
Midday Thaw
10:00 AM to 3:00 PM
The safest travel window. Look for "bare pavement breakthrough" as solar heating melts snow.
Evening Refreeze
3:00 PM to 7:00 PM
Shadows expand across sun-thawed lanes. Wet surfaces transition to gray as water converts back to ice.
Build Your Winter Dashboard
Save a custom route of cameras along your commute to monitor conditions from your driveway to the office.
CREATE YOUR ROUTE →Regional Winter Priorities
- Northeast Corridor: Prioritize coastal bridge checks where salt spray and wind exposure create rapid icing.
- Midwest Plains: Monitor for "ground blizzards" where clear skies exist but wind-blown snow creates zero visibility at road level.
- Mountain West: Check cameras at different elevation gradients (Valley vs. Summit) to track rain-to-snow transitions.

START MONITORING NOW →Can traffic cameras see black ice at night?
Only indirectly. Watch for the reflection of headlights on the road surface; a mirror-like reflection at sub-freezing temps is a definitive indicator of ice.
How often should I check cameras during active snowfall?
Every 15-20 minutes. Winter conditions can change from "wet" to "treacherous" in the time it takes to drink a cup of coffee.
Do the cameras show if chains are required?
Yes, many mountain pass cameras are positioned to show official WSDOT/CDOT signage and can verify if vehicles are currently stopped in chain-up areas.
What is the single best indicator of road safety on camera?
Traffic speed. If vehicles are moving at 20 mph on a 65 mph highway, the road is far more dangerous than it may visually appear.
