PHOENIX (AP) —
Authorities can’t prosecute Arizona motorists for driving under the influence of marijuana unless the person is impaired at the time of the stop, the state Supreme Court ruled Tuesday in the latest opinion on an issue that several states have grappled with across the nation.
The ruling overturned a state Court of Appeals decision last year that upheld the right of authorities to prosecute pot smokers for DUI even when there is no evidence of impairment.
