The Affidavit of Attachment of Sidecar is a crucial document in the Philippines' transportation regulatory framework, particularly for motorcycle owners who modify their vehicles with sidecars. This document is required when registering modified motorcycles with the Land Transportation Office (LTO) and local government units. It serves multiple purposes: documenting the technical specifications of the modification, declaring compliance with safety standards, and providing legal protection for both the owner and public safety. The affidavit includes detailed information about the motorcycle, sidecar specifications, installation details, and ownership declarations. It's particularly important for both personal use and commercial applications, such as tricycle-for-hire services, which are a common form of public transportation in many Philippine communities.
