The bill amends Chapter 31-14 of the General Laws, which pertains to speed restrictions, by introducing a new section titled "School bus speed limit." This new provision establishes that no school bus, as defined in existing law, shall be operated on a limited access highway, as defined in 31-1-23, at a speed greater than ten miles per hour (10 mph) below the posted speed limit. The act is set to take effect immediately upon its passage.
