When you're changing lanes, how should you observe the surrounding area?

Explanation
Correct answer: By looking in the mirrors and turning the head slightly in order to eliminate the so-called "blind spot".
The D-14 "End of lane" sign indicates the need to change lane. Safely performing this manoeuvre requires ensuring that you will not impede vehicles travelling in the lane you intend to enter. Observing the road solely in your mirrors is insufficient due to the so-called 'blind spot'. Therefore, it is also necessary to briefly turn your head to verify that no other vehicle is in this area.
