What is the purpose of the "move over" law in South Dakota?

The "move over" law in South Dakota is designed to enhance the safety of emergency responders and other public safety personnel working on or near the roadside. When an emergency vehicle, such as a police car, fire truck, or ambulance, has its lights flashing or is otherwise engaged in a response, drivers are required to either change lanes to provide a buffer or, if changing lanes is not possible, slow down significantly as they pass the scene. This helps to protect the emergency responders who may be outside of their vehicles and also reduces the risk of accidents involving oncoming traffic.

In contrast, the other options address different driving regulations that do not relate to the specific safety needs of emergency personnel. Changing lanes for motorcycles does not carry the same level of safety concern as the "move over" law aimed at protecting emergency workers. Stopping for red lights is a fundamental traffic regulation that applies universally, while imposing fines on speeding vehicles is part of enforcement rather than a direct response to the presence of emergency services on the road. Thus, the correct answer accurately captures the intent and function of the "move over" law as it pertains specifically to emergency situations.
