A white square sign with a left-turn arrow inside a red circle with a red slash.

A white square has a red circle with a slash across it. What kind of message is this?

  1. A permissive message: it says what you may do
  2. A prohibitive message: it says what you must not do
  3. A warning of a hazard ahead
  4. A guide to a place
Show answer

Correct answer: A prohibitive message: it says what you must not do

The red circle and slash mean the symbol inside is not allowed. This is a prohibitive sign.
