Which of the following scenarios would NOT require a UD-10 report?

A collision between two bicycles would not require a UD-10 report because this type of incident typically falls outside the criteria that warrant such reporting. The UD-10 report is used to document motor vehicle accidents, and since bicycles are not classified as motor vehicles, accidents involving only bicycles do not necessitate this form.

In contrast, the other scenarios listed involve motor vehicles either colliding with other vehicles, pedestrians, or fixed objects, which are generally subject to reporting due to the potential for significant damage, injury, or liability. Each of these situations can have legal implications and may require documentation to ascertain responsibility and insurance coverage, making the reporting essential in those cases.
