What is the violation when a person disposes of litter within 300 feet of a highway at an unapproved site?

The correct choice is rooted in the concept of illegal dumping, which specifically refers to the act of disposing of waste materials in unauthorized locations. When a person disposes of litter within 300 feet of a highway at a site that has not been approved for such disposal, it constitutes a clear act of illegal dumping. This activity not only poses environmental hazards but also violates traffic and public health regulations designed to keep highways and surrounding areas clean and safe.

Illegal dumping is taken seriously because it can lead to significant negative impacts on the environment, local wildlife, and community aesthetics, as well as potentially affecting public health and safety. It is crucial to dispose of waste correctly and at designated locations to mitigate these risks and comply with the law.
