Which of the following situations would be considered a reportable non-collision crash?

A reportable non-collision crash refers to incidents that result in damage or potential danger without an actual collision occurring between vehicles. In the context of this question, all of the scenarios provided fit this definition.

A single vehicle roll-over occurs when a vehicle overturns without involving another vehicle; it is significant enough to be reported because it involves a hazardous situation and potential injuries.

When a vehicle strikes a stationary object, such as a pole or barrier, it also counts as a non-collision crash. Though there is an impact, it does not involve another moving vehicle, making it a situation that should be reported for traffic records.

Additionally, the damage to a parked vehicle without another vehicle involved also qualifies. This may result in damage that could create hazards for other drivers if not reported and addressed.

Thus, all of these scenarios could lead to safety concerns and warrant a report, making the correct answer an inclusive one that acknowledges the necessity of reporting for various non-collision scenarios.
