Final answer:
Jersey barriers are indeed used for security purposes around buildings to prevent vehicles from getting too close, serving as a protective measure against threats or accidents.
Step-by-step explanation:
True or False: Jersey barriers may be placed around buildings to prevent vehicles from getting too close to the buildings. The statement is true. Jersey barriers, also known as K-rails in the western United States, are heavy or portable concrete or plastic barriers that are used to redirect traffic and protect pedestrians and property. They are commonly placed strategically around high-risk or sensitive buildings as physical security measures to create a perimeter that prevents vehicles from getting too close, which may be a concern for vehicle-borne threats or accidental crashes.
Examples of their use include protecting government buildings, military bases, and other critical infrastructure. Their design makes them effective at absorbing and diffusing crash energy, thereby reducing the impact of collisions and enhancing safety.
