What is the blood alcohol concentration threshold for the high PCA range?

The blood alcohol concentration (BAC) threshold for the high PCA (prescribed concentration of alcohol) range is set at greater than 0.150. This level indicates a significant impairment of driving ability and carries severe legal consequences. In New South Wales, a BAC above this threshold is considered a serious offence, as it reflects a considerable risk both to the driver and to public safety.

This threshold is aligned with laws designed to combat dangerous driving behaviors associated with high levels of intoxication. Drivers in this range are likely to experience severe impairments in coordination, decision-making, and reaction time, which escalate the danger on the roads. Therefore, the legal system imposes strict penalties on offenders caught with a BAC greater than 0.150 to deter such reckless behavior and enhance road safety.

Understanding the ranking and implications of different BAC levels is crucial for both law enforcement and drivers, as it shapes accountability measures and promotes public awareness regarding the dangers of driving under the influence.
