The offence of DUI or Driving Under the Influence of intoxication liquor or a
drug is created by section 12(1) of the Road Transport (Safety & Traffic
Management) Act 1999 and states as follows:
(1) A person must not, while under the influence of alcohol or any other drug:
(a) drive a vehicle, or
(b) occupy the driving seat of a vehicle and attempt to put the vehicle in
motion, or
(c) being the holder of a driver licence (other than a provisional licence or a
learner licence issued under the Road Transport (Driver Licensing) Act 1998 ),
occupy the seat in or on a motor vehicle next to a holder of a learner licence
who is driving the motor vehicle.
It can be seen therefore in respect of a DUI offence involving alcohol, that a
person might not be over the prescribed limit of 0.05 and yet driving under the
influence of alcohol (DUI). There must be some observed signs by a witness that
in their opinion, the person was so affected, that the court can draw the
inference that the person was driving under the influence of alcohol (DUI).
Such observations of erratic driving, combined with observations of the person
displaying outward signs such as being unsteady on his feet, bloodshot eyes,
slurring his words, having trouble putting the key into the ignition etc. all
combine to conclude that the person was driving under the influence (DUI).
