Smoke in the Rear of a Loaded Coach
You are driving a 51-passenger coach at 60 mph on an interstate at 02:15 with 44 passengers, many asleep. A passenger runs forward and says there is smoke coming from the rear restroom area. In your mirror you see a light gray haze in the rear third of the cabin. You are 0.4 mile from an exit with a truck stop; the shoulder is narrow with a guardrail. The fire extinguisher is mounted by the driver's seat.
1. Sequence your actions from the moment you confirm smoke, and explain the order.

First, control the vehicle: signal, decelerate smoothly, and get off the travel lane onto the shoulder or, better, to the exit if you can reach it without delay - a 0.4-mile run at 60 mph is roughly 24 seconds, which is short enough to justify the exit where you have room and a safe place to unload. Do not brake hard with unrestrained sleeping passengers. Stop, set the parking brake, shut off the engine, and keep the keys. Then assess: if there is visible flame or dense smoke, evacuate immediately rather than fighting the fire. Order matters because evacuation cannot begin safely until the bus is stopped and secured, and passengers cannot be moved into traffic.
2. You decide to evacuate. How do you use the exits, and what is your role?

Announce clearly and calmly: fire, leave everything, move to the front door or the emergency exits. Use the front door as the primary exit and the rear/side emergency windows or roof hatch as secondary if the smoke is between passengers and the front. Direct passengers away from the vehicle and upwind, and well off the travel lane - the guardrail side is not a safe gathering point. Assign two capable passengers to help anyone with limited mobility. Take a headcount against the 44 you counted at boarding, and report to the 911 dispatcher whether everyone is accounted for. You do not re-enter a burning vehicle for belongings.
3. When would you use the extinguisher, and when would you not?
Read the worked answer
Use the extinguisher only on a small, contained fire you can reach from outside or from the doorway, with a clear escape path behind you, and only after evacuation is underway or complete. You do not go into the rear of a smoke-filled coach to fight a fire - smoke is the killer, and a restroom-area fire in a coach usually means the fire is already inside structure you cannot see. If the haze is growing and passengers are still aboard, evacuation takes priority over extinguisher use every time.
