There are two basic types of taco trucks; the first and most common is the transient truck which is a truck that stops at approximately 20 different locations at 20-minute intervals during an 8-hour shift, typically beginning at 6am and ending at 2pm. The second type is the semi-permanent truck, which is a truck that has found a location that has a density of clientele to sustain it for an extended period of the day, creating a nearly fixed presence in a particular community.
