The Adelaide, Australia Magistrates Court today overturned a speed camera fine issued to a local businessman because it wasn't clear which speed limit applied at a busy intersection. The ruling sets the stage for hundreds of motorists to appeal their tickets after they were caught in the same speed trap.

In July, Rene Spruyt received a A$567 ticket in the mail when his Holden Commodore went across West Tce into Sir Donald Bradman Drive, which has a 60km/h limit. At the same intersection, Grote Street has a 50km/h limit. The speed camera applied the 50km/h limit for the citation.

"We now also have the ludicrous situation where people turning left or right from Grote Street into West Tce are able to do 60km/h, but those going over Grote Street into West Tce have to do 50km/h until they reach the 60km/h zone on Sir Donald Bradman Drive," Police prosecutor Senior Constable Bill Kerins told the Townsville Bulletin.
