  3. 149
  4. Correct answer: 306

Why this is the answer

The correct answer in the official bank: 306

Sign 135 is a warning sign that tells drivers a pedestrian crossing is ahead. The sign that follows it is 306, which is placed at the crossing itself and marks its exact location. Warning signs come before a hazard to give time to slow down, and the sign marking the spot itself appears afterwards.
