So long as such conduct is prohibited by the Pennsylvania Vehicle Code, motorists who own or operate vehicles within the city limits shall operate, maintain, title, register, and license vehicles in accordance with the provisions of the Vehicle Code.

A police officer or law enforcement officer may initiate a motor vehicle stop and, at their discretion, cite a driver for a violation of a primary violation observed within the City of Philadelphia without observing any other Pennsylvania Vehicle Code violation.
(3) Enforcement of Secondary Violations. To the full extent of Council's legislative authority, a police officer or other law enforcement officer may initiate a motor vehicle stop for a secondary violation observed within the City of Philadelphia only where there is a simultaneously-observed primary violation for which an officer, at their discretion, could issue a citation.
