Reports by other motorists on the M1 Motorway of dangerous behaviour by a B-double truck driver led to his arrest for low-range drink driving.
Tuggerah Lakes Highway Patrol responded to concerns about the northbound truck having a number of near misses with other vehicles as it veered in and out of its lane.
At about 4.30pm on Thursday, September 5, the highway patrol located the truck as it approached Morisset and observed the same manner of driving as reported.
The 51-year-old male driver was stopped by police and breath tested, returning a positive result.
He was arrested and conveyed to Toronto Police Station for a breath analysis, returning a reading of 0.059.
The truck driver was also subjected to an oral fluid test which returned a positive detection of Methylamphetamine.
His licence was immediately suspended and confiscated.
The man was issued with a field court attendance to appear before Wyong Local Court for the offence of driving with low range PCA and police said further action would be taken upon confirmation of the oral fluid sample from the police laboratory.
