Quick take: Severe weather creates real injury risk (crashes, falls, and catastrophic events). It also creates legal exposure for drivers and property owners if reasonable precautions aren’t taken.

Black ice is the winter hazard you don’t see until you’re already sliding. The National Weather Service describes black ice as ice that’s difficult to see and often looks like wet pavement. This guide covers Pennsylvania and New Jersey precautions for drivers, homeowners, businesses, and pedestrians—plus what to document if you’re injured.

Edelstein Law links (PA & NJ)

Part 1: Drivers — protect yourself and reduce “defendant risk”

1) Drive for conditions, not the posted limit

In PA, the vehicle code requires driving at a speed that is “reasonable and prudent under the conditions.” In NJ, “unsafe” or “careless” driving can attach when drivers fail to use due caution and endanger others. Bottom line: on ice, a driver can be legally “too fast” even under the limit.

2) Clear snow and ice from your whole vehicle

Both states penalize drivers when snow/ice isn’t removed and later dislodges, especially when it causes damage or injuries. Clearing only the windshield is not enough—roof and hood matter.

3) Winter driving habits that actually prevent crashes

  • Increase following distance and brake early.
  • Avoid sudden inputs—smooth steering and braking are safer on black ice.
  • Assume bridges and ramps freeze first.
  • Use headlights in snow/low visibility.
  • Carry an emergency kit (blanket, charger, flashlight, water, traction aid).

Part 2: Homeowners and businesses — reduce slip-and-fall risk (and legal exposure)

1) Pennsylvania: “Hills and Ridges” doctrine (why timing and accumulation matter)

In many PA snow-and-ice cases, courts apply the “hills and ridges” doctrine. These cases often turn on whether ice/snow accumulated in ridges or elevations, whether conditions were generally present in the community, and whether the property owner had notice and reasonable opportunity to address it.

2) New Jersey: “Ongoing Storm Rule” for commercial properties

NJ’s Supreme Court adopted the “ongoing storm rule” in Pareja, generally relieving commercial landowners from a duty to remove snow/ice during an ongoing storm—shifting responsibility after a reasonable time once precipitation ends.

3) Practical property precautions that matter

  • Shovel early, then shovel again—melt/refreeze is where black ice forms.
  • Salt/sand high-traffic areas (steps, ramps, entrances, mail routes).
  • Fix repeat ice sources (downspouts, drains, leaks) that create “unnatural” icy patches.
  • Use mats + signage at entrances; tracked-in water refreezes.
  • Document your efforts (photos, timestamps, invoices, logs).
  • Preserve video if you have cameras—many systems overwrite quickly.

Part 3: Pedestrians — prevent falls and protect a claim if you’re hurt

Black ice “trap zones”

  • Shaded sidewalks and north-facing steps
  • Areas near downspouts/drainage paths
  • Parking lots and curb cuts where meltwater refreezes
  • “Wet-looking” patches early morning and at dusk

If you fall: do these three things

  1. Get medical care (fractures and head injuries aren’t always obvious immediately).
  2. Document conditions (photos/video of ice, lighting, lack of salt, warning signs).
  3. Report and preserve (incident report; request video preservation if a business has cameras).

Part 4: Catastrophic winter incidents to take seriously

  • Multi-car pileups triggered by black ice and low visibility
  • Pedestrian strikes when drivers lose traction near crosswalks
  • Falls causing TBI on untreated steps/ramps
  • Flying ice from vehicle roofs causing windshield penetration events
  • Carbon monoxide poisoning from blocked vents or unsafe heating

FAQs: Snowstorms, Black Ice, and Liability in PA & NJ

What is black ice and why is it so dangerous?+
Black ice is ice that’s difficult to see and often looks like wet pavement. It can cause sudden loss of traction for drivers and pedestrians. (See the National Weather Service guidance linked above.)
Can I be liable if snow or ice flies off my car and causes a crash?+
Potentially, yes. Both PA and NJ penalize failure to remove snow/ice from vehicles, and consequences increase when dislodged ice causes injury or damage. Clear the roof, hood, lights, and mirrors—don’t stop at the windshield.
If someone slips on my sidewalk, am I automatically liable?+
Not automatically. Liability depends on the facts and state-specific doctrines. In PA, many snow/ice claims involve the “hills and ridges” doctrine. In NJ, commercial cases may involve the “ongoing storm rule,” often shifting duties after a reasonable time once precipitation ends.
What should I document after a winter crash or slip-and-fall?+
Photos/video of ice/snow conditions, lighting, footprints/tire tracks, warning signs, vehicle positions, and any plow/salt evidence. Get witness info and seek medical evaluation. If a business is involved, request preservation of surveillance footage immediately.
Where can I find winter safety guidance from official sources?+
Start with PennDOT and NJDOT/NJOEM, and the National Weather Service: links are included above in this guide.
