What Does “Act of God” Mean in a Car Accident Case?

Who is Legally Responsible

When you’re involved in a car accident, determining who is legally responsible often comes down to questions of fault, negligence, and foreseeability. But what happens if no one is at fault—if the cause was completely out of human control? That’s where the legal concept of an “Act of God” comes into play.

Defining an Act of God

In legal terms, an Act of God refers to a natural event that occurs without human intervention and could not have been prevented or predicted with reasonable care. Common examples include:

  • Flash floods
  • Earthquakes
  • Lightning strikes
  • Sudden severe storms
  • Wildfires caused by natural causes (e.g., lightning)

If such an event directly causes a car accident, the driver might not be held liable—provided they were otherwise driving responsibly.

How This Affects Car Accident Liability in Arizona

Arizona is a comparative fault state. This means fault in car accidents can be divided between multiple parties. However, if the accident was solely the result of an Act of God, a driver may avoid liability altogether.

For example, if a massive dust storm in Lake Havasu causes zero visibility and leads to a multi-car pileup, the parties involved may not be considered negligent—especially if they were following traffic laws and reacting appropriately to conditions. But the situation can quickly change if a driver was speeding or failed to pull over safely.

Not a Catch-All Defense

It’s important to note: Act of God is not an automatic excuse. The defense must prove that:

  1. The event was entirely natural and unforeseeable.
  2. The accident would have occurred even if the driver had exercised reasonable care.
  3. There were no contributing human factors (e.g., distracted driving, bald tires, or mechanical failure).

If any human negligence contributed to the crash—even in a storm—the defense may not hold.

Real-World Scenarios

Imagine a driver in Scottsdale is struck by a falling tree during a microburst. If the tree was healthy and there was no warning, this may be deemed an Act of God. But if the tree was visibly rotting or the property owner had been warned about its condition, liability could shift toward human negligence.

Or consider a driver hydroplaning on wet roads during monsoon season. If they were speeding or driving on worn-out tires, they might still be found at fault—even though the rain was natural.
