The bill amends Section 31-22-9 of the General Laws in Chapter 31-22, titled "Miscellaneous Rules," to enhance regulations regarding debris on highways and roadways. It prohibits individuals from throwing or causing to be blown onto any highway or roadway various hazardous materials, including glass bottles, nails, tacks, and now explicitly includes grass and grass clippings. The language has been updated to replace "upon" with "or cause to be blown onto," emphasizing the responsibility of individuals to prevent debris from entering roadways. Additionally, it mandates that snow removal from driveways must not leave snow in a condition that poses a hazard on the highway or roadway.

Furthermore, the bill requires the director of transportation to post signs informing the public about the penalties for violating these regulations. Violations will incur fines as specified in § 31-41.1-4. The act is set to take effect immediately upon passage, reinforcing the importance of maintaining safe and clean roadways for all users.
