2. Lane change should be done in two stages: First deviating and then communicating with the other drivers.
3. You should pass to the other lane through the shortest diagonal distance and as quickly as possible.
4. Correct answer: First perform a check and glance at the mirrors, then check the lane you want to pass to, verify that you can pass to it and then deviate moderately (diagonally) to the other lane.
