Which of these is true about mirror adjustment?

Adjusting your mirrors before starting a trip is essential for ensuring that you have the best possible visibility and safety while driving. This allows the driver to have a clear understanding of the surroundings, including blind spots, which is critical when navigating in and around other vehicles. Properly adjusted mirrors contribute to safer lane changes and overall driving awareness, reducing the risk of accidents.

While it may seem convenient to adjust mirrors while driving, this practice can be dangerous and lead to loss of focus on the road. Adjusting mirrors after the trip has started can lead to distractions and a diminished attention to driving, which is why it is recommended to make all necessary adjustments before departing.

Furthermore, adjusting mirrors while the trailer is not straight can lead to an incorrect setup, as proper alignment is crucial for seeing the surroundings correctly. Lastly, while technicians can assist with mirror adjustments, it is primarily the driver's responsibility to ensure their mirrors are set for optimal viewing conditions before hitting the road.
