Please pull your vehicle over to the side of the road . Please roll down your window .   What's the matter , sir ?   Have you been drinking ?   No , I haven't sir .   Really ? But I can smell alcohol on your breath . Blow into this breathalyzer , please .   But , sir , I didn't drink at all .   If you refuse to blow , you'll receive a much severer punishment .   OK . I'll blow .   Your BAC exceeds the legal limit .
