Police said the 48-year-old was driving a commercial passenger bus when stopped at a random traffic operation on Sunday night.

The driver has been served with a notice to appear for traffic offences.

Police allege just after 6pm on Sunday, his passenger bus was diverted into a RBT station south of Alice Springs.

The male driver was subject to a roadside drug test which returned a positive result for cannabis, police allege.

The man was arrested and taken to the Alice Springs Hospital for further tests.

He was issued with a notice to appear in court at a later date.

Sergeant Conan Robertson from Road Policing Command said: "We have to be concerned that this is happening in our community, this was a full sized bus, with passengers who were unaware of the risk that the driver posed to them."

"Having a vehicle of this size being driven by someone with a drug in their blood is also a huge risk to other road users and any small mistake could have been catastrophic."
