Transporting a weapon in a vehicle can establish constructive possession if the individual has knowledge of and the ability to exercise control over the firearm. Even if the weapon isn’t physically on them, having it within reach or stored in a location they control implies constructive possession.
For example: A driver who keeps a gun locked in the glove compartment of their personal vehicle is deemed to have constructive possession of that firearm, even though it’s not directly on their person.
