During lane changes, which of the following should be prioritized?

Prioritizing the act of checking the rearview and side mirrors is crucial for safe lane changes. This practice allows drivers to assess their surroundings effectively, ensuring there are no vehicles or obstacles in their blind spots and confirming that the lane they wish to enter is clear. By doing so, drivers can make informed decisions and reduce the risk of collisions.

The other activities mentioned, such as video recording the lane change, closing your eyes briefly, or changing the radio station, can distract from the primary task of driving and compromise safety. None of those actions contribute positively to maintaining awareness of the road and the actions of surrounding vehicles. Hence, the emphasis on mirror checks underscores their importance in ensuring a safe driving experience.
