Approved screening equipment detects cannabis in a G2 driver's body. The driver has a medical authorization for cannabis but is visibly impaired. Which statement is accurate?
The authorization automatically cancels both the zero-drug condition and impaired-driving law
The exception applies whenever any prescribed drug is detected
Police must be satisfied about legal authorization and the matching drug; impairment remains illegal✓Correct answer
The exception applies only if the driver has no licence
Explanation
Medical authorization is not automatic clearance: the officer must be satisfied that use is legally authorized and that the detected drug is the one authorized. Even when those predicates support the zero-drug exception, visible impairment remains prohibited, so the automatic-clearance claim fails.
