Which action constitutes littering under traffic code regulations?

Littering is defined as the act of disposing of waste improperly, specifically in public areas where it is not allowed or designated for waste disposal. Tossing a paper sack out of the car window fits this definition perfectly, as it involves discarding waste onto the road or roadside, which is considered a violation of traffic code regulations regarding littering. This behavior not only harms the environment but also poses potential hazards to other drivers and pedestrians, showcasing untidy public spaces.

In contrast, leaving trash in the trunk of a car does not constitute littering since it is not disposed of in an improper manner; it is contained within a vehicle. Using a designated trash bin is the appropriate action to take and is actively encouraged to prevent littering. Parking a vehicle on the street also does not involve waste disposal and therefore is unrelated to the definition of littering in this context.
