If you are caught selling a car without inspection, you could face fines and penalties, including a $1,000 fine, 6 months in jail, and the loss of your license for 1 year.
There are some exceptions to this rule. For example, if you are selling a car to a dealer, the dealer is responsible for getting the car inspected before it can be sold to another person. Also, if you are selling a car to a person who is not going to register it in Pennsylvania, you do not need to have the car inspected.
