Before the advent of specialised instrumentation for the measuring of Blood
Alcohol Concentration (BAC) in an individual, the common charge brought against
the drink driver was DUI.
This expression which simply means Driving Under the Influence of intoxicating
liquor has become a generic term for Drink Driving.
Since the early Seventies, in Australia, various instruments were created for
the measuring of alcohol in one's breath at the roadside, such as the ampoule
which contained yellow crystals which when the breath was passed through, turned
green. If the colour changed above a certain line on the ampoule, the driver was
considered to have an alcohol level above the permissible concentration and was
then arrested and taken to the police station where he was submitted to a
scientific instrument which gave an accurate reading of his BAC.
In our modern society, much has changed. Police have powers to pull any driver
over and breath test him, claiming it to be a Random Breath Test. Police are
also armed with far better equipment for roadside breath testing, which is also
far more accurate than in previous years.
DUI now has a more extended meaning than 30 years ago, and for some years now
has included those who drive under the influence of not only alcohol, but also
those under the influence of Drugs. (See web page on DUI )
PRESCRIBED CONCENTRATION OF ALCOHOL
The more usual expression now for the Drink Driver who is caught and charged by
the Police is PCA. This simply means that such person has driven a motor vehicle
with the prescribed concentration of alcohol.
In New South Wales we have five distinct concentrations which are prescribed as
a "range" and are as follows:
- (a) Novice Range PCA
- (b) Special Range PCA
- (c) Low Range PCA
- (d) Middle Range PCA and
- (e) High Range PCA
