In our view, if you look at the evidence from some of the other jurisdictions that have random breath testing—most of the European Union countries now have it, as the EU has recommended that it be applied to all their member states—the deterrent effect will in fact address the workload problem. You will in fact have fewer people potentially charged with impaired driving or fewer people involved in serious motor vehicle collisions as a result of driving impaired, because of the deterrent effect of the fear of apprehension. If people believe that every time they go out they have the chance of getting stopped in a roadside check and we have the type of enforcement that has been discussed, the likelihood is that the behaviour is going to change significantly.
