Question 164 in the bank

Is it obligatory to signal while deviating to the right or to the left from the driving lane?

  1. It is not obligatory to signal while deviating from one lane to the other.
  2. It is not obligatory to signal during an insignificant deviation from the lane.
  3. Correct answer: It is obligatory to signal before any deviation from the driving lane, until it is completed.
  4. It is not obligatory to signal if the deviation is significant and noticed by all drivers

Why this is the answer

The correct answer in the official bank: It is obligatory to signal before any deviation from the driving lane, until it is completed.

Any deviation from your driving lane, to the right or the left, must be signalled in advance and the signal kept on until the move is completed. Signalling warns other drivers and pedestrians of your intention before you act, giving them time to react. There is no exception for small deviations, nor for large ones that seem obvious, since you cannot know that everyone has noticed.
