Key Points
Law only requires a clear view down both sides of your trailer.
Flat mirrors show true distance; convex mirrors give a wider view.
Two convex mirrors are completely legal.
The Mirror Debate
Flat mirrors show true distance but feel useless half the time. Convex mirrors give a much wider view - far more helpful for towing.
What the Law Says
The law doesn’t care which type you use. It only says you need to see four metres out and twenty metres back down both sides of your trailer.
The Practical Choice
Two convex mirrors? 100% legal, practical, and far easier to tow with.
