White square sign with a red circle and slash over two cars side by side

A white square sign has a red circle and a bar over an action. What must you do?

  1. Do the action with extra care.
  2. Do the action only at night.
  3. Not do the action in the circle.
  4. Do the action only on a highway.
Show answer

Correct answer: Not do the action in the circle.

A red circle with a bar bans the action inside it. Here the action is passing, so you must not pass.
