This question was answered by our Experts on the Arrive Alive website:
A layman’s definition for a Public Drivers Permit (PDP) is a permit that was issued pre 1998 to drivers of vehicles that operated on public roads who generated income.
A Professional Driving Permit (PrDP) replaced the PDP . The purpose of the PrDP was to expand the scope of drivers that had to be medically sound and display an impeccable driving record. This is to ensure that the drivers who are mostly on the road or transport dangerous goods or are entrusted with transporting many passengers at once have satisfied the legal requirements of being medically fit and not having a criminal record relating to driving or behavior towards people.
You can apply for a PrDP at any Driving Licence testing centre (DLTC). The cost for a PrDP differs in each province. If you tell me where you wish to apply I could provide you with the current cost for a PrDP.
You will have to take you ID, 4 photos and complete form PD1 at the DLTC. Once you have paid the application fee you will be issued with a form MC that has to be completed by a medical practitioner. You will also be referred to the nearest SAPS station for a criminal record check.
