Clause 11 - Power to require specimens of breath at roadside or at hospital etc.
Road Safety Bill
2:30 pm

Mr Greg Knight (Shadow Minister, Environment and Transport; East Yorkshire, Conservative)
I rise to support the thrust of the argument put forward so eloquently by my hon. Friend the Member for Christchurch (Mr. Chope) and in particular to ask the Minister to focus on amendment No. 54.
The practice is adhered to by the police because it is common sense. It saves them wasting their time; clearly, if they administer a breath test to someone who has consumed an alcoholic drink only seconds earlier, the reading will be over the limit and they will go through the process of arresting someone who, it will transpire, is probably under the limit. The 20-minute rule is an important one. Although my hon. Friend made the point that someone who is given a breath test within the 20 minutes will not suffer the injustice of being found guilty when they are under the limit because of the procedure that takes place at the station, there is nevertheless the injustice of being arrested and having one's liberty withdrawn, even if only for an hour or so. That important provision has served us well.
I am aware from my previous incarnation as a lawyer that where someone is stopped by the police and reveals to them that he has had a drink only five minutes previously, the police often make a judgment while they are waiting for the 20 minutes to elapse by speaking to the driver. On at least three occasions, to my personal knowledge, the police have concluded in that period that the driver was clearly cogent and not over the limit. They then changed their minds, aborted the process and let the driver proceed on his way.
I hope, even if the Minister does not want us to put this on the face of the Bill, that he will give the Committee an assurance that this practice of the 20-minute wait between the drink and the administering of the test—a good practice—will continue.
