Every Nebraska winter brings the same headlines: a semi jackknifes on I-80 in blowing snow, a chain-reaction pileup in fog near the Platte, a tractor-trailer slides across the median on black ice. And almost every time, the first explanation offered is the same: it was the weather.
Bad weather is real. But when a fully loaded semi crashes in it, the weather usually isn't the only thing that went wrong. Federal law expects professional drivers to adjust to the conditions, and sometimes to stop driving altogether.
What the federal rule actually says
The Federal Motor Carrier Safety Regulations include a rule written for exactly this situation. 49 CFR § 392.14 requires "extreme caution" whenever hazardous conditions, such as those caused by snow, ice, sleet, fog, mist, rain, dust, or smoke, adversely affect visibility or traction. It goes on:
- Speed shall be reduced when those conditions exist.
- If conditions become sufficiently dangerous, the driver must stop, and may not resume until the truck can be operated safely.
Read that again. The rule doesn't say "drive the speed limit." It doesn't say "keep up with traffic." It says slow down, and if it's bad enough, park it. A truck driver who pushes on through a whiteout at highway speed to make a delivery window is not a victim of the weather.
Notice, too, that the rule doesn't wait for a road closure or a "no travel advised" bulletin. The duty to slow down starts when snow, ice or fog affects what the driver can see or how well the tires grip. The call to stop belongs to the professional behind the wheel, in real time.
Federal rules and Nebraska's own traffic laws stack together
Truckers don't get to pick the easier rulebook. Under 49 CFR § 392.2, every commercial motor vehicle has to be run according to the laws of the state it's driving through. And when a federal motor carrier regulation "imposes a higher standard of care" than the state law, the driver must follow the federal rule.
Nebraska's own rules point the same direction. Neb. Rev. Stat. § 60-6,185, the basic speed law, measures speed against "the actual and potential hazards then existing," and it names "weather or highway conditions" as one of the special hazards that call for a safe and appropriate speed. The posted limit on I-80 is a ceiling for a dry afternoon, not permission to run near it through sleet.
Following distance matters too. Neb. Rev. Stat. § 60-6,140 bars following "more closely than is reasonable and prudent," with "due regard" for traffic and "the condition of the roadway." Two other parts of that statute hit trucks directly, on roads outside a business or residential district:
- A driver pulling a semitrailer who is following another vehicle pulling a trailer or semitrailer may not follow it "more closely than one hundred feet."
- No driver may follow a highway maintenance vehicle closer than one hundred feet when it is plowing snow or spreading salt or sand and is displaying a flashing amber or white light.
That last one is a true winter rule. Plows work in exactly the conditions where a tailgating semi can't stop.
Why drivers push through anyway
In many truck cases I look at the schedule as closely as the snow. Delivery appointments, tight hours, dispatchers who want the load moving, pay by the mile. Those pressures don't disappear when the forecast turns. That's why a weather crash often becomes a case about the trucking company's decisions, not just the driver's. My page on driver qualification and hours of service covers how those records come into play.
The regulations reach the company here too. 49 CFR § 392.6 says no motor carrier shall schedule a run in a time frame that would force the truck to go faster than the speed limits along the route. That rule is about posted limits, not weather. But when a delivery plan only works if nobody slows down for the storm, I want to know who made the plan.
And it's not only the carrier. 49 CFR § 390.13 says no person shall "aid, abet, encourage, or require" a motor carrier or its employees to break the federal safety rules. Whether a shipper or broker leaned on a carrier to get a load through a storm is a question worth asking. I've written separately about when the trucking company and the broker share the blame.
The hours-of-service "adverse driving conditions" exception
The federal hours-of-service rules have a bad-weather exception. Under 49 CFR § 395.1(b)(1), a driver who runs into adverse driving conditions and can't safely finish the run within the normal driving limits may drive "not more than two additional hours" to complete the run or to reach a place of safety.
Two things about that exception matter in a crash claim.
First, it's narrow. The definition in 49 CFR § 395.2 covers snow, ice, sleet, fog and similar conditions only if they "were not known, or could not reasonably be known" to the driver right before starting the duty day or coming off a qualifying break, or to the carrier right before it dispatched the driver. A blizzard that was in every forecast for two days before the truck left the yard is hard to fit inside those words.
Second, it extends driving time. It doesn't suspend the duty to drive carefully. Nothing in the hours-of-service exception cancels § 392.14. A driver using extra hours to get through a storm is a tired driver in a storm, and that combination deserves a close look. My post on truck driver fatigue and hours of service explains why the clock matters so much.
The evidence that answers "it was the weather"
The trucking company will build its weather defense quickly. The answer to it is evidence, and much of it can disappear if nobody asks for it early:
- The truck's electronic data: speed, braking and throttle in the moments before the crash.
- Dispatch messages and delivery schedules: was the driver told to keep going, or warned to stop?
- Weather and road reports: what conditions were known, and when.
- Other drivers: did cars and other trucks slow down or pull off when this one didn't?
- Dashcam footage from the truck and from nearby vehicles.
I explain how to preserve that evidence on my truck crash evidence preservation page.
Reading the records against the weather
The point isn't just to collect those records. It's to lay them side by side on one timeline.
- Speed against conditions. A truck holding cruise speed for twenty miles while visibility collapsed never "reduced speed."
- The duty log against the storm. A driver who passed three truck stops or exits where he could have pulled off is in a different spot than one caught between exits by a sudden squall.
- Messages against the forecast. If the cab got a weather warning at 6 p.m. and the crash came at 7:30 with no slowdown in between, that gap matters.
- Road reports against the crash time. Nebraska posts road conditions through its 511 traveler information system, and weather service records show what was falling and when.
Answering "black ice" and "act of God"
The winter defense usually boils down to one claim: nobody could have seen it coming. Black ice, a sudden whiteout, an "act of God." Some weather really is sudden. But the questions that test the claim are concrete:
- Was ice predictable? Temperatures near freezing, wet pavement and a bridge deck are the textbook setup. Professional drivers know to expect it there.
- What were other drivers doing? If cars were creeping along at 35 and the semi passed them at 65, the road wasn't a secret.
- How long had it been bad? A storm building for an hour along the route isn't a surprise in its last mile.
When the answers point to warning signs the driver ignored, "it was the weather" becomes "it was the driver's choice in the weather."
A hypothetical: two trucks, same storm
This is a made-up example, not a real case. Freezing drizzle starts west of Lincoln on a January evening. Two semis are eastbound on I-80, a few miles apart.
The first driver drops to 40 with his flashers on, has room to stop when a car spins out ahead, and soon parks at a truck stop until the sand trucks come through.
The second driver's data shows him at 68, close behind a pickup. His dispatcher had asked earlier whether he'd make a morning appointment in Des Moines. When the pickup brakes for a stalled car, the semi can't stop.
Same road, same ice. The weather explains the slick pavement. It doesn't explain 40 versus 68. That difference is where liability lives.
Winter pileups are more complicated
Bad-weather crashes on the interstate often involve more than two vehicles, and the second and third impacts can cause the worst injuries. Sorting out who hit whom, and in what order, takes work. I've written about secondary crashes in interstate backups, and my I-80 crash page covers the corridor where so many of these happen.
What to do after a winter crash with a semi
In winter, the evidence literally melts. If you're able:
- Stay safe first. Standing on an icy shoulder beside moving traffic can be more dangerous than staying buckled in with your hazards on. Call 911.
- Photograph the road surface. Snowpack, slush, sand or no sand. Plows and sun can change it within an hour.
- Capture the truck. Company name, DOT number on the door, trailer number, final position.
- Note the mile marker and the time. Those tie the crash to weather and road-condition records later.
- Get witness names, especially drivers who slowed down or pulled over.
- Get checked out. Cold and adrenaline can hide injuries.
Then call a lawyer quickly. Here's how trucking company rapid-response teams get to work within hours.
Mistakes that hurt winter truck claims
- Treating "weather" on the police report as the final word. It describes conditions. It isn't a finding that nobody was at fault.
- Chatting with the trucking company's insurer. An offhand "the roads were terrible" can be turned into a claim that you were the one going too fast.
- Waiting until spring. By then, dispatch messages and electronic data may be overwritten or "lost."
If a winter truck crash took someone you love, my page on wrongful death claims in Nebraska explains how those cases differ.
Why truck crash victims call me
Trucking companies have lawyers and investigators working the case almost immediately. You deserve someone working just as hard for you. I know the federal regulations, I know where the data lives, and I don't accept "it was the weather" as an answer when the rules required the driver to slow down or stop. My clients have recovered more than $23 million, with a top recovery of $5.4 million. You can read what they say about me in many five-star reviews, and my firm was voted Best of Omaha for personal injury law in 2025 and 2026.
