The annual inspection is a requirement for all PUJs plying inside the campus to ensure their conformity to traffic safety and smoke emission regulations. A PUJ is required to pass the above carriage and under carriage inspections by the Traffic Management Office and the Campus Maintenance Office, as well as the smoke emission testing by the Department of Environment and Natural Resources (DENR). Only after passing the inspections will the jeepney operator be allowed to apply for the PUJ’s Permit to Operate (PTO).

The Traffic Management Office provides traffic assistance during special events or by request to the University’s academic and non-academic units. Designated TMO personnel help direct traffic flow during special events and provide assistance to motorists inside the UP Diliman campus.
