What is one restriction placed on counties concerning litter accumulation near public highways?

Litter accumulation near public highways is regulated to maintain safety, aesthetics, and public health. The correct answer states that litter cannot be present for more than 30 days. This restriction helps ensure that highways remain clear of debris that can obstruct drivers' views and create hazardous road conditions. By setting a time limit on litter accumulation, counties can proactively manage roadside cleanliness and encourage timely litter removal, thereby promoting a more pleasant environment for both residents and travelers.

The emphasis on a 30-day limit serves as a clear guideline for local authorities and individuals, creating accountability and a standard for maintaining public spaces. Keeping public highways clean not only enhances their appearance but also reflects community pride and promotes environmental responsibility.
