I'd like to know if anyone has knowledge about this. I parked in a loading zone at Monash Uni yesterday which is signed as "Loading Zone 30 minutes 9am-5pm Mon -Sun". I parked around 4:30. When I got back, I had an infringement ticket time-stamped at 4:32. $107! I rang up about it and was told that I don't have a commercial vehicle. I said that it doesn't say that on the sign and was told that it doesn't have to. Everywhere else I've been has had explicit signs so I've known what to do. Has anyone got any clues about successfully contesting this? I implicit signage doesn't stand up unless its a well-known everyday fact.
