Prohibits the person acting as a temporary instruction permit or intermediate driver's license supervisor from being under the influence of alcohol, controlled substances, or marijuana

This bill prohibits individuals supervising drivers with temporary instruction permits or intermediate licenses from being under the influence of alcohol, controlled substances, or marijuana while instructing. It directly affects licensed drivers who accompany permit holders to provide behind-the-wheel training and ensures they remain sober during these sessions. The legislation reinforces existing requirements by explicitly stating that supervisors must not be impaired while occupying the seat beside the driver for instruction purposes. This measure aims to enhance safety by preventing intoxicated supervision during the learning process for new drivers.
