Officers may use traffic control aids and devices. Which of the following is NOT included?

The correct choice indicates that a firearm is not considered a traffic control aid or device. Traffic control aids and devices are tools and equipment specifically designed to facilitate the management of traffic and ensure the safety of both law enforcement officers and the public.

Cruisers, whistles, flashlights, and reflective clothing serve essential functions in traffic management. For example, a cruiser provides mobility and visibility, allowing officers to patrol and control traffic flow effectively. Whistles and flashlights help communicate intentions and gain the attention of drivers, especially in low-light conditions. Reflective clothing enhances an officer’s visibility, particularly at night or during adverse weather conditions.

In contrast, while firearms are crucial for law enforcement officers' safety and self-defense, they are not used as traffic control tools. Their purpose is entirely different and does not align with the objectives of directing or managing vehicular and pedestrian movement on the roadways. Thus, indicating that a firearm is outside the scope of traffic control aids and devices is a clear reflection of its role in law enforcement.
