While you are driving in a roundabout, an emergency vehicle with flashing lights approaches. What must you do?

Don't block a roundabout or any other type of intersection, even if an emergency vehicle is approaching. If an emergency vehicle with flashing lights or sounding a siren approaches while you are driving in a roundabout, continue to your exit, then pull over and let the emergency vehicle pass. Note: At the time of this writing, South Dakota doesn't have any roundabouts, but the South Dakota Department of Transportation is planning several.
