Parking signage is unnecessarily confusing and ambiguous between driveways, where curb is unpainted. It is unclear where the parking zones are on this block. Apparently, there is a sign with arrow which covers this curb, but is constantly misinterpreted as ending at the driveway or in the red zone, especially if other cars have already parked there. The city should add clearer markings. Considering this is in front of a medical center, it's unconscionable the city would continue to ticket patients and their families who are already likely facing hardships. (As I wrote this, yet another van tried to park here, and I told had to tell her this spot was enforced. She said she didn't see signage that applied to this spot.)
