What is the safest way to adjust your vehicle’s mirrors before driving?

Adjusting your vehicle’s mirrors before entering the vehicle is the safest approach. This method allows you to set the mirrors without the distraction of driving, ensuring that you have a clear view of the road and surroundings before you start moving. It helps establish proper visibility, which is critical for safe driving. Moreover, being outside the vehicle provides an opportunity to check the mirrors' angles more effectively, allowing you to see blind spots and other critical areas.

Other options, such as adjusting mirrors while driving or relying on passengers to do it, can distract from the primary task of driving and increase the risk of an accident. Setting mirrors only after starting the engine may lead to a rushed adjustment process and could also distract from the initial focus on driving, which is vital when getting on the road. Therefore, taking the time to adjust mirrors before you even enter the vehicle is a proactive safety measure that helps ensure optimal visibility.
