Disqualified learner hit 220km/h in pursuit, failed drug test: police

The 24-year-old Victorian, who police say later returned a positive result for methamphetamine in a roadside drug test, came to the attention of patrolling Griffith officers on the Sturt Highway.

He was allegedly detected travelling at 150km/h on the 110km/h highway west of Hay around 9.30am on Friday.

However, instead of stopping when police hit their warning lights, the green 2006 Ford Falcon allegedly sped off.

Police began a pursuit of the vehicle, which they say reached 220km/h before the chase ultimately ended 18 kilometres later in Hay.

Despite bearing South Australia registration plates, the Falcon was not registered and the driver was a disqualified learner from Victoria.

"[The driver] tested positive for methamphetamine during a roadside drug test," police said.

"Additionally, a knife was discovered in the vehicle."

Further testing results are pending.

The man was charged with driving while disqualified and dangerous driving and not stopping in a police pursuit. He is not to occupy the driver's seat of a vehicle, police said, and is due before Hay Local Court in February.

He was also issued fines for speeding, driving an unregistered vehicle, and knife offences.
