Where should reflectorized vests be maintained for police personnel?

The correct choice indicates that reflectorized vests should be maintained in the trunk of each patrol and investigation unit. This location is ideal because it ensures that the vests are readily accessible to officers who need to wear them while conducting traffic stops or other roadside operations, especially during low-visibility conditions. Keeping the vests in the trunk allows officers to quickly equip themselves with this essential safety gear when they are out in the field, enhancing their visibility and safety.

Storing vests in the glove compartment, in a police station storage room, or in a designated locker at the precinct may lead to delays in accessibility. The trunk provides a practical solution as it is part of the patrol vehicle's operational setup, ensuring that the equipment is on hand whenever officers are on duty.
