Since parking tickets are typically obtained while the driver of the car was away from the car, they are associated with the car registration and not with an individual driving record. When searching for information regarding parking tickets, the ticket number is entered instead of the drivers license number.
If an individual drives a car that is registered to someone else, and that individual receives a parking ticket, the ticket is applied to the registration of the owner of the vehicle. The officer who wrote the ticket has no way of verifying who actually parked the car illegally. This also means that even if an individual did not incur parking tickets that turn up under his registration, he is responsible for paying them and is subject to any legal action that may be taken in collecting payment for them.
