Adds improperly transporting or storing a firearm in a motor vehicle to the offense of unlawful use of a weapon

This bill modifies existing laws to classify the improper transportation or storage of a firearm in a motor vehicle as a specific offense under the unlawful use of a weapon statute. It directly affects individuals who carry loaded, concealed firearms in vehicles without placing them in a locked container or trunk, while also creating exceptions for law enforcement, judges, and other authorized personnel performing official duties. The legislation provides specific exemptions for adults transporting concealable firearms under certain conditions, such as when the vehicle is in a non-functioning state, traveling on a continuous journey, or when the firearm is under the driver's direct control. Additionally, the bill clarifies that transporting an unloaded firearm where ammunition is not readily accessible does not constitute a violation.
