67 Pa. Code § 75.5
An applicant for a driver's license and every driver the Department has reason to believe does not have reasonable and proper understanding of safe driving practices and of the traffic laws governing the use and operation of motor vehicles on Pennsylvania highways shall submit to a general knowledge examination. In the case of an applicant for a driver's license, the questions will relate as nearly as practicable to the class of vehicles for which the applicant desires to be licensed. Questions will be taken from the most recent edition of the Pennsylvania Driver's Manual or related publications for specific classes of vehicles, or both. An applicant who correctly answers 80% or more of the questions shall pass the examination. Cheating, failure to follow the instructions of the examiner, offering bribes or gratuities to the examiner, fraud or misrepresentation constitutes an automatic failure of the general knowledge examination. This test may be waived for drivers with a valid driver's license from this or another state.
