The California Supreme Court ruled that a small amount of loose, scattered cannabis on the floor of a car does not constitute an 'open container' under state law, setting a higher bar for what can be considered readily accessible for consumption while driving.

Why it matters

This decision provides clearer guidelines for law enforcement and drivers around the state's cannabis open container laws, which previously had been interpreted more broadly. It aims to distinguish between cannabis that is readily usable for consumption versus incidental remnants that pose no immediate risk of impaired driving.

The details

In the case, Sacramento police pulled over a car for a rolling stop and found about a third of a gram of loose cannabis 'crumbs' on the rear floor. They cited the open container law to search the car, leading to an unrelated gun charge. The court ruled the scattered bits of cannabis did not meet the legal threshold for an open container, as they were not in a state ready for immediate consumption and could not have been easily accessed by the driver or passenger.
