Obviously you would get in trouble for driving without a license. But you can also get in quite a bit of trouble if another unlicensed driver is caught tooling around in your wheels. So stop letting your friends borrow dad’s pickup. We don’t care who they’re buying beer for.

If you are hiring someone to drive a commercial vehicle or to transport hazardous materials (for example, if they are to be carting around potentially harmful works of literature such as Lord of the Flies and The Adventures of Huckleberry Finn), then that person must have the proper license for the job. We doubt anyone reading this guide will currently be in such a position, but you may have minions someday—who knows? Be careful, though; world domination is a tough racket to break into.
