As part of Operation Crown: Roadmap to the New Normal, Random Breath Test (RBT) stations were set up during the afternoon and evening of Friday 15 May 2020 to coincide with the reopening of licensed premises. 

The RBT component of the operation was intended to be highly visible in multiple locations in the Darwin region to deter and detect drink driving and drug driving offences. The operation incorporated members from Road Policing and all major stations in the Darwin region.

688 drivers were tested with all of them returning negative results. One driver was issued a notice to appear in court for medium range drink driving and three drivers were issued with traffic infringement notices for low range drink driving. A traffic infringement notice was issued to a driver for driving with an unrestrained child. Nine drivers were issued with drug infringement notices.

Police issued a notice to appear in court to a 19-year-old male driver with zero alcohol limit conditions on his license. The male had pulled off the road prior to an RBT station on Stuart Highway in Yarrawonga and hid in scrubland prior to handing himself into the custody of police.
