If a passenger becomes disruptive or threatens safety, the driver should:

A disruptive passenger threatens the safety of the driver and other passengers. The correct response: pull off the road in a safe location (not the shoulder of a busy highway unless no alternative); set the parking brake and turn on hazard lights; calmly address the passenger; call dispatch or 911 if the situation cannot be resolved or if there is a credible threat. Do not engage physically or argue at length while driving — driver attention belongs on the road. Some companies have specific protocols for handling disruptive passengers; know your company's policy. Continuing to drive with an unresolved threat in the cabin endangers everyone.
