The screening test is not intended to give a precise measure of a suspects alcohol levels, it is used to indicate whether the level is likely to exceed the prescribed drink drive limit. Preliminary breath test readings are not used as admissable evidence for the basis of a prosecution in a court of law.................If a driver is arrested for suspected drink driving he will then be required to undertake an evidential breath test. Evidential breath testing machine readings ARE used as admissable evidence for the basis of a prosecution in a court of law."
