Which traffic sign should be placed at an intersection, after passing traffic sign 139 that is displayed in the following picture?

- 303
- 307
- Correct answer: 302
- 301
Why this is the answer
The correct answer in the official bank: 302
Sign 139 is a warning sign that tells you in advance that sign 302, the stop sign, is placed ahead at the intersection. The black octagon inside the triangle hints at the stop sign's shape. At the intersection you must come to a full stop and give way. Sign 301 only requires giving way without a mandatory stop, so it is not the answer.
