Question 377 in the bank

Which warning sign is sometimes placed before traffic sign 302?

Five numbered signs: inverted white red-bordered triangle (301); red-bordered triangles with pedestrian on stripes (135), black octagon (139), exclamation mark (150); red octagon with white hand (302).
  1. 135
  2. 301
  3. Correct answer: 139
  4. 150

Why this is the answer

The correct answer in the official bank: 139

Sign 139 warns in advance that sign 302, which requires a full stop, is placed further along the road. This lets the driver prepare and slow down before reaching the stop sign. Sign 301 is not a warning sign but a yield sign, and signs 135 and 150 warn of other hazards.
