No cap, but a choice you made at the insurance counter
Pennsylvania constitutionally prohibits caps on compensatory damages for injury or death, so pain and suffering is for the jury. In car accident cases, the limited tort election in 75 Pa.C.S. 1705 restricts noneconomic damages unless the injury meets the serious injury definition.
Fault follows 42 Pa.C.S. 7102, with the Fair Share Act's 60% threshold for joint and several liability.
