What is an ‘Act of God’ in Arizona Car Accident Law?
FREE CASE REVIEW FREE CASE REVIEW ⟶Table of Contents:
When a car accident happens in Arizona, the first question is usually “Who is at fault?”. But what if no one is directly responsible? What if the crash was caused by something completely outside human control — like a sudden dust storm, flash flood, or lightning strike? In the legal world, this type of event is often called an “Act of God.”
At Big Auto Accident Attorneys, we help car accident victims understand their rights in every situation — including those where Mother Nature plays a role. If you’ve been hurt in an accident and the other side claims it was an “Act of God,” here’s what you need to know.

Defining an 'Act of God' in Arizona Law
In Arizona, an “Act of God” refers to an unavoidable event caused solely by natural forces, without human intervention. These events are typically:
- Unpredictable (not something a reasonable driver could anticipate)
- Unpreventable (no amount of reasonable care could have avoided the accident)
- Caused by nature (not by human error or negligence)
Examples include:
- Sudden monsoon rains leading to flash flooding on I-10
- A violent dust storm (“haboob”) reducing visibility near Phoenix or Casa Grande
- Lightning strikes or fallen trees during desert storms
- Earthquakes or other rare natural disasters
If an accident is truly the result of one of these forces, liability may be limited or eliminated. But insurers often misuse this defense to avoid paying claims.
When 'Act of God' Does Not Apply
The key issue is whether the accident was entirely unavoidable. If human negligence played any role, the “Act of God” defense may not hold up. For example:
- A driver speeding through a dust storm and causing a pileup cannot escape liability.
- A trucking company that fails to maintain tires or brakes can’t blame a rainstorm for a blowout.
- A city that neglects to repair dangerous roads may still be held responsible, even if weather makes conditions worse.
In Arizona courts, if negligence combines with natural forces, the negligent party may still be liable for damages.
How Insurance Companies Use the Defense
Insurance carriers are quick to deny or minimize claims by calling an accident an “Act of God.” They may argue that:
- No one could have predicted the event
- Their insured driver wasn’t negligent
- Damage was entirely caused by weather or natural forces
This is why having an experienced Arizona accident lawyer is critical. At Big Auto, we know how to push back against these arguments and show when negligence really played a role.
Evidence That Can Make or Break Your Case
To prove whether an accident was avoidable or not, attorneys gather evidence such as:
- Weather reports and ADOT advisories at the time of the crash
- Police reports from Arizona DPS or municipal officers
- Eyewitness testimony about driver behavior during the event
- Vehicle inspection reports to determine if mechanical failure played a role
- Road maintenance records if government negligence is suspected
This evidence often makes the difference between an insurance denial and full compensation.
Damages Available in 'Act of God' Accidents
Even when natural forces play a part, you may still be entitled to compensation if negligence is involved. Potential damages include:
- Medical expenses and rehabilitation
- Lost wages and reduced earning potential
- Pain and suffering
- Property damage
- Wrongful death in fatal accidents
If the accident was truly unavoidable, your recovery may depend on your own insurance coverage — such as collision coverage or uninsured motorist protection.
Arizona Roads and Natural Hazards
Arizona drivers know that extreme weather is a real threat. According to the Arizona Department of Transportation (ADOT), dust storms and flash flooding cause numerous crashes every year. Highways like I-10, I-17, and Loop 101 are especially vulnerable to sudden weather shifts.
Because of these risks, courts and insurers expect drivers to take reasonable precautions — slowing down, pulling over, or avoiding travel during severe conditions.

- Investigate all possible sources of negligence
- Challenge unfair insurance denials

- Fight for your right to compensation in Arizona courts
