What is the meaning of the following traffic sign?

- Dead-end street ahead.
- Give right-of-way to crossing vehicles.
- Instruction road sign: Drive right only.
- Correct answer: T-junction ahead.
Why this is the answer
The correct answer in the official bank: T-junction ahead.
A red-bordered triangle is a warning sign, and the black symbol inside shows your road ending at a crossing road, meaning a T-junction is ahead. Slow down and prepare to turn left or right. It is not an instruction sign, which is round and blue, and not a dead-end sign, which is a blue rectangle.
