Which type of vehicles does not qualify as street rods?

Dune buggy-type vehicles do not qualify as street rods because they are typically built for off-road use and do not conform to the standards and criteria applied to street rods. Street rods are generally defined as modified vehicles that often have a vintage aesthetic but are enhanced for performance and safety to meet road-use regulations. They are commonly based on older model cars and are equipped with various updates, making them suitable for highway operation.

In contrast, reconstructed vehicles involve the rebuilding of previously junked vehicles to meet safety and emissions guidelines. Specially constructed vehicles are those built for specific purposes but still adhere to street regulations. Vintage cars, while they may be similar in appearance to street rods, are often categorized based on age rather than the modifications that define street rods. Thus, dune buggy-type vehicles stand out, as their purpose and construction do not align with the street rod classification focused on on-road operation and compliance.
