Mirrors and blind-spot checks work together, but they are not interchangeable. Mirrors help you monitor traffic behind and alongside the vehicle, while a blind-spot check helps you see areas that mirrors cannot cover. K53 documentation defines observation as including mirror use and blind-spot checks to establish whether it is safe to the rear, front and sides. Before changing lanes or moving away from the kerb, use your mirrors to assess the overall traffic situation. Then check the blind spot on the side you plan to move toward. This quick shoulder check is especially important for motorcycles, cyclists and smaller vehicles that can be hidden from mirror view. Do not turn your head away from the road for too long. The goal is a brief, purposeful check followed by a smooth manoeuvre only if the space is clear. Repeating this sequence during lessons builds a reliable habit: mirrors, appropriate signal, blind spot, then move when safe.

Frequently Asked Questions
Why is a blind-spot check needed if I used my mirrors?
Mirrors cannot show every area beside the vehicle. A blind-spot check helps identify vehicles or road users hidden from view.
When should I check my blind spot?
Before changing lanes, moving away from the kerb, merging or making a sideways movement.
Which blind spot should I check?
Check the side you intend to move toward. For example, check right before moving or changing lanes to the right.
Can motorcycles be hidden in a blind spot?
Yes. Their smaller profile makes careful mirror and blind-spot observation especially important.
