It is a bit tricky on the liability shield for a corporation. If the entity (LLC/corporation/etc.) makes a bad investment, the creditors cannot come after your personal assets (assuming you haven't put up a personal guarantee). If one of your employees has an expensive accident while driving for you, exceeding your insurance, they can only take the assets of your entity. BUT if you are driving that company vehicle and hit the school bus, they can sue you personally for your personal mistakes, even though you were on company business.
