hey guys-
i spoke to another friend (a police officer here in newcastle) and he informed me that unless it is a stationary speed camera, if you are pulled over you will not recieve a fine.
this is due to the fact that the officer cannot prove who the driver was.
in the case of stationary speed cameras, they have enough evidence for you to supply a stat dec saying who the driver was.
if there is no photo, and no recording of who the driver was at the time, it is not enough evidence to a summary (traffic) offence.
