You may be denied coverage because you are driving for pay. You need to find out before you have a claim. A claim could be relatively cheap car repairs after vandalism, or it could be expensive medical bills for several people after a multi-car accident. It is impossible to spell out the difference here between personal and business use of a car. Each insurer defines the difference its own way, and so do the regulations of each state. My goal is to make you aware that your insurer draws a line, and that you need to know where this line is. I have seen coverage denied on dozens of these claims. You could lose your house, your retirement savings, your children's college funds, and any other assets you have.
