Supreme Court held that driving while intoxicated by alcohol and another drug proves knowledge of the latter's effects.

The Supreme Court ruled that a driver found intoxicated by both alcohol and another drug was deemed to have known the effects of the latter. The prosecution argued that the combined impairment necessitated an inference of knowledge regarding the specific drug's impact. The court accepted this reasoning, establishing that simultaneous intoxication by multiple substances creates a presumption of awareness of all involved impairments.
