Answer 1

1), which is to ensure there are no vehicles in the blind spot when changing lanes, and it is also important for checking for any other potential obstacles or hazards.

Step-by-step explanation:

The correct answer is option 1) To ensure there are no vehicles in the blind spot. When changing lanes, it's essential to perform visual checks to the left or right to make sure that there are no vehicles in your blind spot, which are areas around the car that cannot be seen via rearview and side mirrors.

Additionally, these visual checks also serve to 2) check for any obstacles or hazards that may be present in the adjacent lane. While signaling is indeed crucial to indicate your intention to change lanes, the act of physically looking is not utilized to signal this intention but to ensure safety.

Therefore, the most accurate and overarching reason for looking left or right before changing lanes encompasses both ensuring there are no vehicles in your blind spot and checking for other potential hazards.
