Question 538 in the bank

What is the meaning of the following traffic sign?

A green circle with a white ring and thin green outer border, showing white Hebrew letters above the word GO. Meaning: Proceed carefully (hand held sign).
  1. Correct answer: Proceed carefully (hand held sign).
  2. Drive fast.
  3. Drive without stopping. Stopping is prohibited.
  4. Stop and wait for the instructions of the traffic flagger.

Why this is the answer

The correct answer in the official bank: Proceed carefully (hand held sign).

This is a hand-held sign. The word "Go" on its green side permits you to continue driving. The instruction is to proceed carefully, so it is not an instruction to drive fast. Stopping and waiting for the flagger's instructions is also not the instruction of a sign that permits you to proceed.
