What is a critical consideration when adjusting mirrors before driving?

Adjusting mirrors before driving is crucial for ensuring a clear field of vision and minimizing blind spots. Blind spots are areas around your vehicle that cannot be seen in your mirrors, and they can pose significant hazards when changing lanes or merging into traffic. Properly positioned mirrors help drivers to see vehicles approaching from behind or alongside that might otherwise remain hidden. This adjustment promotes safety by giving the driver a comprehensive view of their surroundings, allowing for more informed decision-making while on the road.

Enhancing style, showing passengers better, or entertaining while driving do not contribute to the functional safety of driving. In fact, focusing on aesthetics or distractions rather than safety could lead to hazardous conditions on the road. Thus, avoiding blind spots is the primary goal when adjusting mirrors, making it a fundamental aspect of vehicle preparation before driving.
