In a blow to the autonomous trucking industry, the California Senate passed a bill Monday that requires a trained human safety operator to be present any time a self-driving, heavy-duty vehicle operates on public roads in the state. AB 316, which passed the senate floor with 36 votes in favor and two against, still needs to be signed by Gov. Gavin Newsom before it becomes law. Newsom has a reputation for being friendly to the tech industry, and is expected to veto AB 316.
