Hypothetically, let's consider someone who does not own a car and does absolutely no personal driving. He or she might, on occasion, accept a ride from a visiting family member, but this would happen three or four times in a year. This person would probably be considered car-free, at least by most here.

Now let's add in one factor. This person has a Class 1 driver's license and works as a truck driver for an oil company, delivering gasoline to service stations in the region. With this added factor, is the person car-free, car-light or something else?

Before writing this off as an extreme example, I have met someone like that. The person I've met was someone who built up a lifestyle for himself where the personal use of a car was unnecessary, but he worked in a job where he spent his time driving.
