An Early Warning Device (EWD) is a safety or compliance device installed on motor vehicles as mandated by LOI 229 and monitored under regulations such as MC-92-146, typically for notification of violations or vehicle status.
There are ten accredited manufacturers/dealers of EWD listed in the memorandum, each assigned specific code ranges for their validation stickers.
The Executive Director and Chairman of the EWD Committee, Augusto B. Araneta, Jr., is responsible for adopting and enforcing the accreditation of manufacturers and dealers of EWD as per the memorandum.
Sumerian Industries was assigned the code 'AA' with the serial number range from 1000001 to 1250000 for their EWD validation stickers.
GJB Enterprises located at 7637 Guijo St., Makati, Metro Manila, is assigned the code 'BB' with serial numbers from 1250001 to 1500000.
Accreditation authorizes these entities to manufacture or distribute Early Warning Devices and ensures that only authorized devices with assigned serial numbers are valid for use, thus complying with legal and regulatory safety standards.
The memorandum involves multiple locations such as Valenzuela, Makati, Mandaluyong, Pasay City, Quezon City, Dagupan City, and Urdaneta Pangasinan, showing the geographical scope of accredited manufacturers/dealers under the Land Transportation Office.
The assigned serial numbers and codes help in identifying and authenticating the EWDs, preventing use of counterfeit devices and ensuring compliance with LOI 229 regulations.
LOI 229 and MC-92-146 are laws and memoranda circulars concerning vehicle regulation, including mandates for the use of EWDs; the memorandum indicates that these laws are fully implemented by regulating and accrediting manufacturers/dealers of EWDs.
