Yet a policeman might wish to do the testing, believing that the person had driven to the bar.The person had driven to the bar, left the bar, taken a taxi home, and not broken any laws, but because the person was drunk as a skunk and the policeman knew that he or she had driven to the bar, the policeman could still subject the citizen to the test.
Pourtant, un policier pourrait vouloir procéder au test, croyant que cette personne a pris une voiture pour aller au bar. Si cette personne a pris sa voiture pour aller au bar et a quitté le bar en taxi, elle n'a enfreint aucune loi.
