You need a car because most clients are not on a bus line. They may send you out 20 miles or more from your home. So be expected to have a car where you're driving all over for 3-5 hour shifts, using your gas and mileage and wear and tear on your vehicle. You need a car daily because they send you to different clients at different locations. Sometimes you're sent to a client's home or a nursing home where they live. So those of you who live on a college campus with no car or who only use public transportation, this is not a good job for you.
