Does the hon. Lady not agree that the argument about breathalysers and seat belts in relation to the last trial back in 1968 to 1971 is slightly flawed? Seat belts were not compulsory until 1983, and in my experience very few people used them before that time. In the same way, people did not take a great deal of notice of the breathalyser in the early days of the drink-drive laws.
I do not entirely agree. Although it was not compulsory to wear a seat belt, they were fitted in cars in that period, and I think people did take note of the breathalyser, because prosecutions were made.
