Madam, - Tony Allwright (February 16th) is correct in suggesting that properly targeted random breath-testing will act as a deterrent.
The level of prosecutions for drink-driving shows that a significant number of motorists believe that they can currently drive a potentially lethal weapon, when over the legal alcohol limit, with little possibility of detection.
Regardless of civil liberties, I suggest that if such breath-testing succeeds in changing this mindset, any occasional inconvenience to innocent motorists will surely be considered worthwhile. - Yours, etc,
