Practice question

What is the purpose of 'Mirror-Cam' (Digital Camera Mirror Systems) replacing conventional glass side mirrors on modern passenger coaches?

To provide a complete view with no blind area or failure mode, so direct observation is unnecessary
To provide an approved rearward field of view on interior displays, potentially adding low-light processing, reference lines and reduced aerodynamic drag while still requiring the driver to manage contamination and blind areas
To record the road only after a collision, without providing a live driving image
To replace the windscreen view during forward manoeuvres

Answer: B — To provide an approved rearward field of view on interior displays, potentially adding low-light processing, reference lines and reduced aerodynamic drag while still requiring the driver to manage contamination and blind areas
