While driving through a long tunnel, smoke starts coming from your engine compartment. The car can still be driven normally. What is the most appropriate action?
💡 Hint
Smoke fills a tunnel quickly and there is little room to escape. The right response depends on whether the car can still move, so weigh what danger stopping inside the tunnel or turning back would create for the vehicles behind you.
Answer: ②
Explanation
Smoke fills a tunnel quickly and there is little room to escape, so if the car can still move, the safest course is to warn others with the hazard lights and drive out of the tunnel. Stopping in the middle of the lane traps the cars behind, and a U-turn or aggressive overtaking inside the tunnel causes further crashes. If you cannot go on, pull over to the edge, switch off the engine, evacuate via an emergency exit and report it.
