UK road signs library

A quick visual reference grouped the way the test thinks about signs: by shape and colour. For the system behind them, read our road sign families guide.

In the UK, red triangles warn, red circles prohibit, blue circles give positive instructions, and rectangles inform. Learn the shapes and you can read almost any sign.
