The term PROM CONVEYANCES can be summarized as vehicles used to transport people to and from proms. The most common of these are limos, which is a five letter word. Limos are luxury cars that are often rented for special occasions such as proms, weddings, and other formal events. They are typically long and black in color, and are often decorated with ribbons or other decorations. Limos are usually chauffeured, meaning they are driven by a professional driver.
