What is probable cause?

What is probable cause?

• A. The main event or condition that led to the accident.
• B. The weather conditions on the day of the incident.
• C. A contributing factor that is not determinative.
• D. The last action taken before the incident.

Answer: (A)

Probable cause is the primary reason the accident occurred—the main event or condition that started the sequence of events leading to the crash. In investigations, this is the factor without which the accident likely would not have happened, even though other contributing elements may be present. Weather conditions on the day can influence safety, but they aren’t by themselves the probable cause unless they were the decisive trigger. A last action taken before the incident is part of the sequence but doesn’t by itself identify the initiating factor. A contributing factor that is not determinative is an additional element that helped the situation but didn’t cause the accident on its own. So the best answer points to the main event or condition that led to the accident.
