Adjusting all mirrors for the best visibility is a crucial step before starting your driving trip. Properly positioned mirrors provide drivers with a clear view of their surroundings, which is essential for safe maneuvering, lane changes, and being aware of blind spots. Taking the time to ensure that mirrors are aligned correctly enhances the driver's field of vision, significantly reducing the risk of accidents caused by unseen vehicles or obstacles.

In contrast, setting the GPS while driving is dangerous and can distract the driver from the road. Ignoring weather conditions can lead to poor decision-making, as adverse weather can greatly affect driving conditions. Leaving your phone on for notifications can also serve as a distraction, pulling attention away from the essential task of driving. Overall, ensuring visibility through proper mirror adjustment is a proactive safety measure that lays the foundation for a successful journey.
