The 41-year-old male driver was not injured.

He underwent a roadside breath test and a drug test which both returned a positive result.

During a search of the car, police allegedly found a substance believed to be cocaine as well as cannabis and prescription medication.

The man was arrested and taken to a police station where he underwent further breath and drug tests.

The breath test returned an alleged reading of 0.162, while the drug test was again positive.

The man was charged with high-range PCA, possess a prohibited drug and custody of a knife in a public place.

His licence was also suspended.

“Further charges are dependent on the outcome of the drug test,” NSW Police said.

He was granted conditional bail to appear in Katoomba Local Court in July.
