It’s a bitter January evening. Snow falls thick and fast, coating everything in sight — including the traffic lights at a busy intersection. A driver approaches, but the stoplight is completely obscured by snow. Unsure whether to stop or go, they hesitate, nearly colliding with another car already in the intersection.
This scenario isn’t rare. Snow-blocked traffic signals are a major hazard during winter storms, especially since modern LED stoplights don’t emit enough heat to melt accumulated snow and ice. Unlike older incandescent bulbs, LEDs save energy but leave intersections vulnerable, leading to dangerous visibility problems.
The consequences are real: missed signals can mean accidents, injuries, and in the worst cases, fatalities. Municipalities and drivers alike face the same challenge every winter — how do we keep intersections safe when snowstorms strike?
In this post, we’ll explore the scope of the problem, review traditional fixes and why they often fall short, and introduce a proven, innovative solution designed for real-world winter conditions. Whether you’re a traffic engineer, municipal decision-maker, or concerned community member, the strategies shared here will help you understand how to make intersections safer in snowy weather.
Why Snow-Covered Traffic Lights Are a Serious Safety Hazard
When heavy snow hits, the risk on the road goes far beyond icy pavement. Snow-covered traffic signals create a silent but deadly hazard. Unlike potholes or slick turns that drivers can see and anticipate, an obscured stoplight gives no warning — leaving motorists guessing at life-or-death decisions in real time.
The problem has grown since the widespread adoption of LED traffic lights in the 1990s. While LEDs are energy-efficient and long-lasting, they don’t generate enough heat to melt snow and ice. As a result, during blizzards or even light snow with high winds, snow can pack into the visor of the signal and block its visibility entirely.
This isn’t just inconvenient — it’s dangerous. According to the Federal Highway Administration, intersections account for over 40% of all traffic crashes in the U.S. When signals are obscured, that number only increases. Communities in northern states and across Canada report numerous near-misses and crashes tied directly to snow-packed traffic lights.
Quick Answer (Featured Snippet Ready):
Snow-covered traffic signals are dangerous because LED lights don’t produce enough heat to melt snow, leaving drivers unable to see whether to stop or go.
Traditional Solutions and Their Limitations
Communities have long struggled with how to keep traffic lights visible during winter storms. Several approaches exist, but each comes with serious drawbacks that make them less than ideal for consistent safety.
Heated Traffic Signals
Some municipalities invest in heating elements built into traffic signals to melt away snow and ice.
- Pros: Effective at keeping lenses clear during heavy snow.
- Cons: High installation and operational costs, constant electricity use, and potential for component failure in extreme conditions.
Manual Snow Removal
In severe storms, road crews may be dispatched to physically clear traffic lights.
- Pros: Direct and immediate fix once crews arrive.
- Cons: Labor-intensive, costly, and dangerous for workers during blizzards. Coverage is often delayed, meaning many intersections remain obscured until crews can get there.
Chemical De-Icers and Coatings
Some areas experiment with anti-icing sprays or chemical treatments applied to signal lenses.
- Pros: Relatively inexpensive upfront and easy to apply.
- Cons: Short-lived effectiveness, potential environmental harm, and limited reliability in heavy snow or high winds.
Innovative Passive Solutions That Work in Real Life
The challenge with most traditional fixes is that they’re reactive — crews must be dispatched, heaters must run, or chemicals must be reapplied. But winter storms don’t wait. Communities need a solution that works automatically, with no ongoing effort or energy costs.
That’s where passive snow-prevention technologies come in. Instead of relying on electricity or manpower, these designs use natural elements like airflow and gravity to prevent snow from sticking in the first place. By channeling wind or altering the surface angle of signal visors, snow is less likely to accumulate and obscure the light.
What makes passive solutions stand out:
- No moving parts → Fewer points of failure.
- No electricity required → Cost savings and sustainability.
- Always “on” → Works the moment the storm begins.
- Minimal maintenance → Once installed, little to no upkeep is needed.
This shift to passive safety measures is gaining traction across North America, especially in snow-prone regions. Municipalities are realizing that the most effective solution is often the simplest.
Spotlight Solution – The Snow Cone by Snow Proof Signals
When it comes to keeping intersections safe during winter storms, one solution is proving itself across the U.S. and Canada: The Snow Cone, developed by Snow Proof Signals LLC.

Real-World Proof
Founder Chris Bichon, a signal electrician since 2006, witnessed firsthand the dangers of obscured LED stoplights. Determined to find a solution, he developed the Snow Cone and tested it in real-world conditions — even mounting signals on pickup trucks and driving through active snowstorms to refine the design.
Why Consistent Testing Is the Key to Success
Most traffic signal solutions fail not because they aren’t well-intentioned, but because they aren’t tested in real-world winter conditions. Snow doesn’t fall the same way every time. Some storms bring wet, heavy flakes that cling to surfaces; others deliver light, powdery snow that can swirl and pack into small crevices.
This variability is why many products look good on paper but fall short when a blizzard actually hits. Consistent, field-based testing is the difference between a theoretical fix and a proven solution.
At Snow Proof Signals LLC, testing wasn’t left to chance. Founder Chris Bichon and his team developed a unique method: mounting traffic signals on the back of pickup trucks and driving through active snowstorms at speeds of 30–55 MPH. This approach allowed the Snow Cone to be exposed to multiple storm types, wind speeds, and snow densities.
The result? A visor designed not for lab conditions, but for the real-world roads your community drives every day.
Best Practices for Winter Intersection Safety
Keeping intersections safe during snowstorms requires more than plows and salt. Municipalities need a layered approach that combines technology, planning, and preventive measures. Here are key strategies to reduce the risk of accidents caused by snow-covered signals:
1. Invest in Passive Safety Solutions
Instead of relying solely on heated systems or manual clearing, communities can save money and lives with passive designs like the Snow Cone. These require no electricity and work automatically, reducing both costs and risks.
2. Prioritize High-Risk Intersections
Focus resources on intersections with:
- High traffic volumes
- Frequent winter weather incidents
- Poor sightlines or complex road layouts
3. Train and Equip Road Crews
Crews should be prepared to respond quickly to severe storms, with clear protocols for snow-blocked signal emergencies.
4. Use Smart Monitoring Tools
Camera systems and IoT monitoring can help identify obscured signals faster, allowing proactive responses.
5. Budget for Long-Term, Low-Maintenance Solutions
Investing in one-time installations like the Snow Cone provides ongoing protection without recurring energy bills or chemical costs.
