Property owners often blow their grass clippings on roadways, and a problem may arise if the grass clippings cause an accident. Some research suggests that grass clippings can be as slippery as grease is on roads, and clippings can be especially dangerous for motorcycles. Ohio does not have laws that explicitly prohibit property owners from blowing grass clippings onto roadways. An Ohio law makes it illegal to place injurious materials onto roads. But this law doesn’t cover glass clippings.
