Which of the following should not be depicted as a traffic unit on a CR-3?

In the context of the CR-3 Traffic Code, a traffic unit typically refers to a vehicle or an object that interacts with roadways in a controlled traffic environment. A deer, while it can be involved in accidents and has implications for road safety, is not classified as a traffic unit in the same context as vehicles or human roadway users like pedestrians and cyclists.

Motorcycles, bicycles, and pedestrians all represent direct users of the roadway who interact with traffic laws, regulations, and safety measures. In contrast, animals like deer do not operate vehicles or have the same traffic implications within the framework of reported accidents or traffic incidents, which is why they should not be depicted as traffic units on the CR-3.

This distinction is important for accurate data collection and reporting in traffic incidents, as it allows for a clearer understanding of how human-operated units interact with the roadway, without mixing in non-traffic units that may complicate the analysis of road safety and traffic trends.
