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 definition for "types of vehicles" and clarifies that trucks with a gross vehicle weight of eight thousand five hundred pounds (8,500 lbs.) or less may be registered as automobiles and issued passenger plates. This change aims to provide more flexibility in vehicle registration for lighter trucks, allowing them to be classified similarly to passenger vehicles.

The bill also includes provisions that address the registration of trucks and tractors, ensuring clarity in the classification of motor vehicles. It maintains existing definitions for various vehicle types, including antique motor cars, motorcycles, and emergency vehicles, while updating the language to reflect current standards. The act is set to take effect upon passage, facilitating the registration process for qualifying trucks and potentially expanding the options available to vehicle owners in the state.
