Prohibits grass clippings from being thrown or deposited upon any highway

This bill amends New York's Vehicle and Traffic Law to explicitly prohibit throwing or depositing grass clippings on any highway. It directly affects residents, landscapers, and others who might dispose of yard waste along roadways. The key provision adds grass clippings to a list of hazardous materials already banned on highways - including glass, nails, and cans - because they could injure people, animals, or vehicles. The law takes effect immediately upon enactment.
