Which term describes symbols showing emergency diversion route for motorway traffic?

• A. Diversion Route
• B. End of Controlled Parking Zone
• C. Entrance to Congestion Charging Zone
• D. Symbols Showing Emergency Diversion Route for Motorway Traffic

Answer: (D)

These signs exist to guide drivers when a motorway section is closed, directing them along an emergency route to keep traffic moving. The term that best describes these symbols is the one that literally names what they show: symbols showing emergency diversion route for motorway traffic. It specifies that these are signs indicating the alternate path to take in an emergency, which distinguishes them from ordinary diversion signs or zone-related signs.

The other options don’t fit because they refer to different concepts: a general diversion route could be used in non-emergency situations and isn’t specific to motorway emergency signs, while the end of a controlled parking zone and the entrance to a congestion charging zone relate to parking controls and charging zones, not to emergency detours on motorways.
