Let's say you are a driving instructor, for example. It's one thing to need coverage in case you get into an accident while conducting a driving lesson. But what if, during the course of your training session, you give improper directions to your student, which in turn causes him or her to get into an accident, resulting in bodily injury or property damage to your student, or to an innocent bystander, or to some property?
That's where public liability insurance comes into play. If you feel that paying for public liability insurance is like throwing money away because it is seemingly too expensive, then you should consider how just expensive it might be if you end up becoming party to a lawsuit due to an accident you caused due to your own professional negligence while on the job.
With the hospital bills and property damage you become liable to pay on behalf of the injured party, not to mention the legal fees associated with defending yourself in court, these costs, if you were to incur them, can end up costing you many times more than the mere pittance you would have to pay for public liability insurance.
