A step van is a specialized class of van designed specifically for multi-stop residential and business deliveries. Step vans are also known as walk-in vans because of the ability to easily walk from the driver seat and into the back where the goods are. In the mid-1930s, step vans were being used as bakery vans, home services vans, and police vans with cells in the back. Over the years, the uses of step vans vary from food vans, ice cream vans, delivery vans, and mail vans.
