Current law requires the owner of a truck to present a manufacturer's certificate of origin or a certified scale ticket if the truck is subject to certain weight-based fees and weighs more than 4,500 pounds but not more than 10,000 pounds. This weight includes mounted equipment other than recreational equipment. The bill makes 2 changes to these requirements: The requirement only applies when the truck's weight has been substantially modified; and The truck must be weighed rather than using a manufacturer's certificate of origin to show shipping weight.(Note: This summary applies to this bill as introduced.)
