vehicles, low speed vehicles, three wheeled vehicles, and tax exempt vehicles. Each category has an obligatory set of requirements and procedures to follow to be fully registered. Renewals are also obligated to submit the necessary requirements and to follow procedures to be fully renewed. The LTO also oversees miscellaneous transactions, specifically transactions requiring change of certificate of registration, and transactions that do not require the change of certificate of registration. Law enforcement and adjudication of cases One of the main functions of the LTO is to strictly implement and enforce the laws regarding land transportation. Necessary requirements and procedures are to be followed in settlements of admitted cases and contested cases of motor vehicles, plates, and driver's licenses. The LTO also follows a strict procedure in settlements of impounded violations. It also allows private and for hire motor vehicles to apply for duplicate plates. Furthermore, the LTO is in charge of ensuring that public land transportation services abide by the fares set by the LTFRB. It has sanctions for the overcharging and undercharging of fares, and for non-issuance of fare tickets. Manufacturers, assemblers, importers, and dealers reporting (MAIDR) The LTO grants accreditation to certain manufacturers, assemblers, importers, and dealers who wish to transact business with the LTO. A firm, person, or corporation must file an application for accreditation with Assistant Secretary of the Land Transportation Office containing certain requirements and qualifications in order to transact business with the LTO relative to Motor Vehicles or its components. It also issues the Certificate of Stock Reported (CSR) which certifies that a motor vehicle or its component has already been reported by its manufacturer, assembler, or importer to MAIDRS. The LTO also requires sales reports that inform the LTO that the reported stock is already sold to the end-user. Sales reports include regular sales transactions and stock transfers. It also reports the issuance of a single CSR, of Motor Vehicles (MVs) formed out of combining components (new, used, or previously registered) MV/MC that are undocumented in a procedure called special reporting. The LTO also maintains the processes that facilitate requests for the approval of the MAID office with LTO related transactions. Such transactions include the issuance of a conduction sticker, a public bidding of a motor vehicle, and the stamping of chassis identification number.
