At California State University Northridge I parked my car in the only remaining three spots that were right next to each other (| | | |). There is a yellow bar that is across the front of all three spots about 3 inches tall and about an inch away from the curb, both the bar and the curb are painted yellow. However, the lines indicating spots are white. In the usual spot at the back of the parking spot a very worn and weathered but still clearly visible, it says, "compact". However more clearly written above "compact" it says "motorcycle parking" in a black box with white lettering. I received a ticket for parking my car in a motorcycle only spot, the ticket says " parked motorcycle only". Is this a valid ticket? Thank you for your help.
EDIT: The vehicle is a 4-door Volvo s40.
