Do you have a car? renewal of registration requires Insurance, CEC (Certificate of Emission Compliance)..etc. PETCs are privately owned testing centers that are accredited by the Philippine government to help protect the air quality. We cannot renew our vehicles registration without passing the test first. Come to think of it the quantity of the motor vehicles here in Cebu and when I pass by the testing centers I could see that there are only few. Is there a possibility of none appearance , are they really effective or its just another scheme to ge a run for our money?
