Massachusetts Registry Of Motor Vehicles (RMV) Practice Test

When approached by an emergency vehicle using a siren or flashing lights while driving in a roundabout, the most appropriate action is to yield to the emergency vehicle immediately. This allows the emergency vehicle to pass through the intersection without delay, which is critical during emergency situations. In a roundabout, it is generally considered unsafe to stop in the middle of the traffic circle or to speed up, as this can create confusion and may lead to accidents. Continuing to your exit and then pulling over to the right is appropriate because it allows you to navigate safely out of the roundabout while still acknowledging the presence of the emergency vehicle. By maintaining a smooth flow of traffic while yielding to the right, you minimize disruption and keep the environment safe for all road users. Thus, this approach is both safe and considerate in a dynamic driving scenario like a roundabout.
