Dr. Declan Bedford:

No, I do not think so. I have to be practical at the same time. Whatever legislation is brought in has to be acceptable. As this is a democracy, I have no particular problem. I do believe that in any case, whatever the level is, the key is highly visible enforcement. Without that, nothing works. That is my own personal view on that. Of course 20 mg would be a good limit. It would make it clear to everybody. When we see people out at night time some think they are fine with a glass of wine or a beer or two and believe they are below the limit and are obeying the law but one cannot be sure. Alcohol affects everybody differently. If the limit was down at 20 mg people would know they definitely could not drink and drive. That would clear it up and they would forget about having the one or two drinks. That might happen.
