The bill amends sections of the General Laws in Chapter 31-1, specifically regarding the definitions and classifications of various types of vehicles. It introduces a new provision that allows trucks with a gross vehicle weight of eight thousand pounds (8,000 lbs.) or less to be registered as automobiles and issued passenger registration license plates. The bill clarifies the definition of a "truck" and specifies that any truck meeting the weight criteria may be registered as an automobile.

Additionally, the bill outlines various vehicle types, including antique motor cars and motorcycles, and establishes regulations for their use and registration. It emphasizes that vehicles over twenty-five years old must meet inspection requirements to be used for activities beyond exhibitions and parades. The act is set to take effect upon passage, streamlining vehicle classifications and registration processes for lighter trucks.
