C Restriction - Prohibits the driver from operating Class A or B passenger vehicles (buses). A Class A or B CDL with the passenger endorsement will carry this restriction unless the driver obtains a passenger endorsement by successfully completing a skills test in a Class B passenger vehicle (bus).

I got that on my license. But i allso have a P endorsement on there to. I called penndot about this and they told me it was there fault and to come back to DMV and they would fix it. I never had the C restriction in till i got my class M so i got a dup. of my license and on the camera card it had it on there right from Penndot. So both of my license had the P endorsement but only the new one about 2 weeks old have the c restriction. Well if they want me to take a skills test i cant i have no way to get a hold of a bus. i just wanted because you never know.
