Since the tragic deaths of four young people in the Sydney suburb of Oatlands, there are renewed calls for the alcohol limit to be Zero.

The current allowable limit is 0.02, and police say the driver of the vehicle that allegedly killed the children returned a reading of 0.150 or three times the legal limit.
