The use of Random Breath Testing (RBT) to deter: individuals from drink dri
ving is seen as one of the major initiatives: in Australian Road Safety. Vi
ewed within the genre of general deterrence models, RBT enters the decision
to drink and drive through increasing, the-perceived risk of being apprehe
nded. Although long term crash statistics point to a possible link between
the introduction of RBT and a reduction in drink driving, a number of resea
rchers have questioned the stability of RBT as a counter measure. This pape
r analyses the deterrence effect of RBT in regional Queensland; an area whe
re the rate of fatal crashes attributed to alcohol is high. The significant
finding reported is that of itself the perceived threat of being apprehend
ed does not significantly deter drink driving.
