Motor Vehicle Traffic Accidents: (Relevant Definitions)
A motor vehicle traffic accident must involve at least one motor vehicle in-transport in which (1) the unstabilized situation originates on a trafficway or (2) a harmful event occurs on a trafficway.
A trafficway is any land way open to the public as a matter of right or custom for moving persons or property from one place to another. Trafficways are bound by the adjacent property lines.
When applied to motor vehicles, in-transport means that the motor vehicle is in motion anywhere within the trafficway boundaries or on the roadway portion of the trafficway (moving or stopped).
