Except very special and rare situations, the driver should be personally liable for a ticket even if on the job. Traffic laws apply to individual drivers and not vehicle owners or contractors.

Parking tickets are not moving violations, and are typically assigned to the car, not to the driver, for obvious reasons.

I have a friend who works as a driver (merchandising, not delivery) and he personally pays for his parking tickets. This is in the UK though, maybe things are different in the US.
