The program, which was launched last Friday, also issued stickers to tricycle drivers reminding them to give priority to the handicapped.
The stickers were also meant to prevent disabled passengers from being charged exorbitant fees by tricycle drivers.
A memorandum was signed by the Mandaluyong City Disabled Persons Affairs Division and a tricycle foundation, which stated that the handicapped should not be discriminated against by public utility drivers.
Mandaluyong city officials said the stickers must be displayed prominently in tricycles to generate public awareness of the rights of disabled persons, as well as remind them of their needs.
Tricycles with the stickers will be allowed to transport emergency cases to hospitals, offices and other areas "without being charged with violations of existing traffic rules" even if they go outside of their designated routes.
The driver will also be exempted from any apprehension by city traffic enforcers when ferrying a handicapped passenger.
Earlier, the city government has established the Accessibility Law Governing Physically-Challenged Individuals.
The ordinance stated that "devices such as the prominent display of posters or stickers shall be used to generate public awareness of the rights of the disabled and foster understanding of their special needs."
"Discriminating against disabled persons in the carriage or transportation of passengers will also be declared unlawful," it said.
