I parked immediately behind a pay to park sign and a car and a half's length in front of a 'handicap parking' sign on the street. I assumed it was just that spot so I made sure my wheels were behind the white spray painted line on the curb assuming that was the border for the spot before the handicapped spot. I returned to find a $250 ticket saying I had parked in a handicapped spot and was told by a passerby that they had turned the whole block into handicap parking but just hadnt clearly labeled it all yet. Should I mitigate this or should I contest it?
