A person can reduce their vehicle's blind spots by adjusting the rear-view mirror to bring the entire back window into view. Adjusting the side mirrors also reduces the blind spots.
To adjust the driver's side mirror, users should sit on the driver's seat and move the mirror a little at a time until the vehicle's left rear backside is visible. To adjust the passenger side mirror, users should lean to the right to position themselves squarely in front of the rear-view mirror. They should then move the mirror slowly until they can see that back right-hand corner of the vehicle.
