You must report an accident if __________________________.

You must report an accident if there is more than $1,000 in damage because this threshold is set to ensure that significant accidents resulting in considerable property damage are documented by authorities. Reporting accidents helps create a record that can be useful for insurance purposes and legal considerations. In North Dakota, reporting helps maintain road safety and accountability among drivers.

The other options suggest lower damage thresholds, situations without injuries, or accidents occurring on private property, which do not meet the established requirement for mandatory reporting in North Dakota. Recognizing the correct threshold is crucial for drivers to understand their responsibilities following an incident.
