K53 warning signs: meanings and what to do

45 warning signs from the South African road signs manual, with how to recognise each one.

Warning signs tell you about a hazard ahead so you can slow down and prepare. They are red-bordered triangles. The K53 learner's test expects you to recognise the sign and pick the correct response, so the table below pairs each sign with the clue that identifies it.
