(1) No vehicle may be parked on the campus except in those areas set aside and designated for parking.

(2) No vehicle may be parked so as to occupy any portion of more than one parking space or stall, except that a vehicle which is larger than one space may also occupy so much of an adjoining space(s) as is (are) necessary and as limited elsewhere in this chapter.
