As a general rule, Tech Wizards technicians should park on the street in front of residential customer’s homes, rather than in their driveway, when on an on-site service call. This is a "general rule" because there may be situations where it makes more sense (or is safer) to park in their driveway. In those cases, still try to park in such a way that you do not block the customer’s vehicle(s) from being able to pull out of their driveway.
