Almost one in seven drivers have returned positive drug tests following a police operation in the Hunter Valley.
Between Friday 15 May 2025 and Sunday 17 May 2026, Highway Patrol officers from across the Northern Region – assisted by the Traffic Response Group – conducted Operation Spoiler.
The high-visibility operation was established in response to high rates of fatal and serious injury crashes and anti-social driving behaviour in the Hunter Valley and Port Stephens areas.
During the operation, officers focused on speeding and impaired driving offences in key areas including Maitland, Cessnock, Singleton and Scone.
As a result of the operation, 7,597 random breath tests were conducted, with 35 tests returning positive results.
A total of 649 drug tests were conducted, with 92 tests returning a positive result. Secondary tests were undertaken for all 92 drivers, and the samples have been sent for further analysis.
1,008 infringement notices were issued, three of those for speeds exceeding 45km/h.
A total of 45 charges were laid for alleged traffic and criminal offences.
Newcastle-Hunter Sector Highway Patrol Chief Inspector Thomas Barnes said the results reflected continued poor decision making by some drivers in the region.
"These figures are deeply concerning and highlight that too many drivers are still choosing to get behind the wheel after consuming drugs or alcohol," Ch/Insp Barnes said.
"Drug driving remains a major contributor to serious crashes, and the fact that nearly one in seven drivers tested returned a positive result is a concern for police and the community."
"Highway Patrol will continue to target high-risk behaviour, including speeding and impaired driving, to keep our roads as safe as possible."
"If you make the wrong decision to drive under the influence, you will be caught."
Similar operations will be planned and conducted across the region.
