Impairment to the Slightest Degree
To prove that you were under the influence of marijuana at the time of your traffic stop, authorities must show what is known in Arizona law as “impairment to the slightest degree.” In other words, prosecutors must show marijuana use impaired your driving, even to the slightest extent. Any traffic citation – as evidence of a driving error – issued by the arresting office could be sufficient to overcome this burden. Officers might also ask you to perform field sobriety tests during the traffic stop as a means of determining impairment.
By law, you do not have to submit to field sobriety tests. Politely decline the request. This right doesn’t usually extend to providing breath, urine or blood samples. If you choose not to cooperate, officers may obtain a warrant for your bodily fluids, which you cannot legally refuse.
