Anyone who drives the Front Range or the open plains of Northern Colorado knows how quickly the elements can turn. From blinding ground blizzards on I-25 to sudden, violent wind gusts sweeping across Highway 392 near Windsor, bad weather is a regular part of life here.

When a massive semi-truck jackknifes or drifts into another lane during a storm, the trucking company’s insurance lawyers almost always jump to the same defense: “It was an Act of God. The weather was entirely out of our control.”

But does Colorado law actually let negligent drivers off the hook just because the weather was bad? The short answer is no. In fact, under both state and federal rules, adverse weather usually shifts more responsibility onto the commercial driver, not less.

The “Act of God” Defense vs. Driver Negligence

In legal terms, an “Act of God” (or an unavoidable accident defense) applies to an event caused entirely by nature that could not have been prevented by human foresight or care. However, Colorado courts set an incredibly high bar for this defense.

To successfully blame the weather, a trucking company must prove that the storm was completely unpredictable and that the driver could not have done anything to avoid the crash.

Here is why that defense rarely holds up in a Colorado winter storm or wind event:

  • Weather Forecasts: Modern truck drivers have access to real-time weather apps, CDOT alerts, and commercial GPS systems. If a high-wind warning or a heavy snow alert had been issued for Weld or Larimer County hours before the crash, the hazard was predictable.
  • The “Act of God” Requires Perfection: If the truck driver was speeding even slightly for the conditions, tailgating, or driving on worn tires, they cannot claim nature was solely to blame. Their own actions contributed to the danger.

The Commercial Driver’s Duty: High Standard of Care

Commercial motor vehicle (CMV) drivers operate rigs that can weigh up to 80,000 pounds. Because these vehicles are so dangerous in a crash, federal and state regulations demand a much higher standard of care from truck drivers than standard motorists.

Federal Motor Carrier Safety Regulation (FMCSR) § 392.14 explicitly addresses hazardous conditions like snow, ice, sleet, fog, mist, rain, dust, or smoke. The rule states:

Extreme caution in the operation of a commercial motor vehicle shall be exercised when hazardous conditions adversely affect visibility or traction. Speed shall be reduced to those conditions.

The regulation goes a step further: If conditions become sufficiently dangerous, the driver is required to stop the vehicle and not resume driving until it can be safely operated.

If a Windsor driver is hit by a semi-truck during a high-wind warning on Highway 392, an experienced Windsor personal injury lawyer will look directly at this rule. Did the driver use “extreme caution”? Did they reduce their speed well below the posted limit? Should they have pulled over at a truck stop or rest area instead of pushing through? If the answer to any of these is “no,” the driver was likely negligent.

How an Injury Attorney Can Combat the “Weather Excuse”

If you are injured in an accident with a semi-truck, proving that the driver ignored weather hazards requires fast, thorough evidence collection. An experienced injury attorney will immediately lock down:

  • The Truck’s Black Box (ECM): This data reveals exactly how fast the truck was traveling, when the driver hit the brakes, and whether they were accelerating into a known hazard.
  • Dashcam Footage: Forward-facing cameras can prove just how bad the visibility or road conditions were, showing whether other vehicles were safely slowing down while the semi-truck pushed ahead.
  • Driver Logs and Dispatch Records: This reveals if the trucking company was pressuring the driver to hit a tight delivery deadline, encouraging them to ignore dangerous weather conditions.

Weather might cause a patch of ice or a heavy gust of wind, but human choice determines how a commercial vehicle reacts to it. Colorado truck drivers are trained and legally required to handle the state’s harsh climate. When they choose a deadline over safety, negligence is the cause of the crash.
