What is the penalty for littering on a public highway in North Dakota?

In North Dakota, littering on a public highway is taken seriously due to its impact on the environment and public safety. The law establishes a penalty structure that aims to deter such behavior. The correct answer reflects this commitment by imposing a significant financial penalty of $500 for littering. This fine serves as a strong deterrent against littering, reinforcing the message that maintaining clean and safe public spaces is a priority for the state.

The other options, such as a warning or community service, do not convey the same level of seriousness regarding littering offenses in North Dakota. Those measures may be relevant in certain lesser violations but are not the standard consequence for littering on a public highway, where the established fine represents the state's firm stance on environmental cleanliness and safety.
