Rollo and Tabs, I appreciate what you are saying, however my point is this - if you are pulled over in the UK, France, Germany, Spain etc for suspected DUI then the first thing that will happen is you are asked to provide a breath sample to see whether you are over the drink-driving limit. Not asked to perform a series of ballet manouvres before this happens. All I wanted to know is if anyone knew, with all the technology available, is why it would appear in the USA, and maybe other countries too, why a suspect is asked to do these moves rather than a straight brealthalyser test. So does anyone know 'cos I'm none the wiser.???
