Final answer:
Oliver is potentially violating Illinois regulations by transporting medical cannabis in unsecured paper bags, which should instead be in a sealed and reasonably secured container while in a vehicle.
Step-by-step explanation:
The question pertains to whether Oliver, a medical cannabis designated caregiver, is violating the Illinois Vehicle Code by transporting medical cannabis in unsecured paper bags in the trunk of his car. Even though medical marijuana is legal in Illinois, there are specific regulations regarding how it should be transported. The Illinois law requires that medical cannabis be transported in a sealed, tamper-evident container and reasonably secured from moving while the vehicle is in motion. By storing cannabis in unsecured paper bags, Oliver could potentially be violating state regulations that pertain to the transportation of medical cannabis.
