What blood alcohol concentration is found in the low PCA range?

The blood alcohol concentration (BAC) found in the low PCA (Prescribed Concentration of Alcohol) range is indeed between 0.050 and 0.079. This range is significant in the context of Australian traffic laws, as it delineates a threshold where drivers are considered to be operating a vehicle while having a low level of alcohol in their system.

In New South Wales, the legal limit for full license holders is 0.05, meaning that any level above this indicates a level of impairment that may affect a driver’s ability to operate a vehicle safely. The rationale behind setting this range is based on studies correlating alcohol consumption with impairment, where even low concentrations can affect judgment, coordination, and reaction times. Therefore, the 0.050 to 0.079 BAC range is critical for law enforcement when determining if a driver may be over the legal limit.

Understanding this information helps clarify why the other options reflect higher BAC levels that are categorized as mid-range and high PCA, which entail different legal repercussions and considerations regarding driving under the influence. The increasing BAC levels correspond to more significant impairment and stricter penalties in New South Wales law.
