Which of the following is considered an emergency vehicle?

An emergency vehicle is defined as any vehicle that is specifically designed and equipped to respond to emergencies. This typically includes vehicles that are used by police, fire departments, and emergency medical services. The police car fits this definition perfectly, as it is equipped with sirens and lights and is used to manage emergency situations, enforce the law, and ensure public safety.

In contrast, while the other options may be essential for various functions, they do not operate in the same capacity as emergency vehicles. A taxi cab and a delivery van are commercial vehicles meant for transport and deliveries, and a city utility truck focuses on municipal services, such as maintenance and repairs. Although these vehicles can sometimes be involved in urgent situations, they are not classified as emergency vehicles under the law, nor do they have the specific authority or equipment reserved for vehicles responding to emergencies.
