Walk It Through: The Siren in the Rain
An ambulance behind, a fire truck on a run, a trooper on the shoulder, and a crossing gate coming down.
An ambulance with a siren and flashing red lights comes up behind in the rain.
Two things a person in this spot might do. Picking one shows what the law says about it.
A drive with no crash, no stop and no charge. The service vehicles the move over rule also covers, and a commercial driver's own crossing duties, stay on their pages.
A practice walkthrough, not a prediction of how any real one will go. Legal information, not legal advice.
