Emergency vehicles refer to any type of vehicle that is specifically designed and equipped for responding to emergencies. These vehicles are typically operated by public safety agencies such as fire departments, police departments or medical services, and their primary purpose is to provide assistance to individuals in need during times of crisis. Examples of emergency vehicles include ambulances, fire trucks, police cars, and rescue vehicles. They often have distinctive flashing lights, sirens, and other visual or auditory signals that alert others on the road to make way for them as they respond to an incident.
