Difficulty: MediumTunnel Emergencies

Your vehicle suffers sudden mechanical failure inside a road tunnel and comes to a halt in an emergency lay-by. After switching on your hazard warning lights and turning off the engine, what action should you take to summon assistance?

  1. A
    Walk back along the carriageway to place a red warning triangle behind your vehicle
  2. Use the nearest emergency roadside telephone to contact tunnel controllersAnswer
  3. C
    Stay seated inside the vehicle and wait for other road users to report the hazard
  4. D
    Keep the ignition turned on to continuously monitor dashboard warning indicators

Answer

Use the nearest emergency roadside telephone to contact tunnel controllers
Using the dedicated emergency roadside telephone connects the driver straight to the tunnel control team. This allows controllers to immediately identify the precise location of the breakdown, activate overhead variable message signs, lower speed limits, or close the affected lane to ensure safety.

Step-by-Step Solution

1
Secure the vehicle and evacuate occupants to a safe area behind the safety barrier or within the designated refuge walkway
Vehicle occupants are placed away from live traffic flow
Safety of life takes precedence over vehicle recovery inside an enclosed tunnel environment
2
Locate and use the dedicated emergency roadside telephone point rather than relying solely on a mobile device
Tunnel operators receive an immediate alarm with precise location telemetry
Emergency tunnel telephones connect directly to regional control centres, allowing operators to close lanes and dispatch emergency assistance swiftly
