Difficulty: EasyTunnel Emergencies

If traffic comes to a complete standstill inside a road tunnel, you should switch off your vehicle's engine.

Answer: Answer

Answer

True. Drivers must switch off their engine when stationary in a tunnel to reduce toxic exhaust fumes and minimise fire risk.
Under the Highway Code, if traffic comes to a complete halt inside a tunnel, drivers are required to switch off their engines to prevent toxic exhaust fumes from building up in the confined area.

Step-by-Step Solution

1
Identify the environmental and safety hazards of stationary traffic in an enclosed tunnel.
Recognise that idling vehicles quickly release toxic gases into a restricted space with limited ventilation.
Maintaining air quality and preventing poisonous fume accumulation inside a tunnel is vital for occupant safety.
2
Apply the official Highway Code procedure for prolonged congestion in a tunnel.
Turn off the engine while keeping a safe separation distance from the vehicle ahead.
Stopping the engine eliminates unnecessary exhaust emissions and reduces the risk of vehicle overheating in an enclosed space.
