How should a driver act when encountering an emergency vehicle on the roadway?

When a driver encounters an emergency vehicle on the roadway, the appropriate action is to move to the right and, if safe and possible, come to a stop to allow the emergency vehicle to pass. This practice is essential for ensuring the safety of both the emergency responders and other motorists. Emergency vehicles, such as ambulances, fire trucks, and police cars, often need to reach locations quickly, and yielding to them can facilitate a faster response time.

The law generally requires drivers to give way to emergency vehicles with activated lights and sirens. Moving to the right creates a clear path for these vehicles, making it easier for them to navigate through traffic efficiently. Stopping (when feasible) further enhances the situation by providing a safe space for the emergency vehicle to maneuver.

Other options presented do not promote safe behavior on the roadway. Accelerating and merging into another lane could create confusion and potentially lead to accidents. Ignoring stationary emergency vehicles poses a risk to emergency personnel who may be working on the road, and stopping only at traffic signals does not account for the necessity of yielding to emergency responders at all times, regardless of signal status. Therefore, option B stands out as the correct and responsible choice in this scenario.
