This is so the fire department can readily get to people who may need their help. A lot of their life-saving equipment is on their fire trucks, and seconds saved could mean the difference between life and death for someone. The fire department can also levy huge fines against the campuses because fire lanes are blocked. I don't see the problem if I park in a loading dock. There usually isn't anyone parked there anyways.
Loading docks are for the purpose of vendors making deliveries, such as food, mail, or supplies.
A lot of delivery companies, if they cannot unload when their trucks arrive, will leave, and it will require another delivery charge for them to come back, often delaying deliveries. All citation fees are collected by the violator's campus and billed to their student accounts. Your vehicle is subject to be towed and removed from campus property. I received a citation that I don't think I deserved. You can appeal a parking citation within 10 days of the issuance date.
