Which incident qualifies as a more severe motor vehicle accident?

A motor vehicle accident that involves injuries is classified as a more severe incident because it indicates that individuals have been harmed as a result of the collision. This severity is assessed based on the potential for medical treatment required, the implications for those involved, and the legal and insurance ramifications that such injuries bring.

In contrast, a minor fender bender typically involves little to no damage and likely doesn't result in injuries. A parked vehicle without damage indicates there has been no impact leading to any consequences, while roadside assistance for a flat tire does not constitute a collision or accident at all. The presence of injuries in a motor vehicle accident signifies a risk to human life and well-being, which elevates the severity and seriousness of the event compared to the other options provided.
