In variable zones the speed limit displayed on electronic signs can vary depending on the time of day and/or traffic conditions.
Cameras in variable zones are linked to these electronic signs and enforce the varying speed limits accordingly.
A small grace period is afforded to motorists at the time of a speed limit change, during which fines may not be issued.
This time period is set by, and at the discretion of, Victoria Police.
Motorists must obey the speed limit at all times.
