What specific observations should a driver make before reversing a vehicle fitted with an external audible warning device?

Correct Answer

Observations should be made to the front; sides and rear of the vehicle; including blind spots.

Explanation: Drivers should not rely solely on an external audible warning device to warn others that their vehicle is reversing. Before reversing; drivers must make sure it is safe to do so by taking all appropriate observations to the front; sides and rear of the vehicle; including the blind spots. Never assume it is safe to reverse just because the vehicle has an external audible warning device.
