Where I park for work free parking spots (for cars) are at a premium. I noticed this week that some students have taken to parking their car on the lawn of their rented house and then use the raised curb as their driveway effectively stopping (or I guess they hope they are stopping) anyone parking on the street in front of this makeshift driveway. What would happen if someone parked on the street in front of this "driveway"? Would they get a ticket or is the parking spot the students have created not a legal one? I'm wondering about this because if all the students started parking their cars on the lawns of their rented houses the free parking on this street would effectively vanish.
