Do the Mirrors Show You Everything
Can I see everything I need to in the mirrors?
No. There are blind spots in the view from every vehicle which are caused by pillars or body of the vehicle. To combat these, you must move yourself in your seat to give yourself the best view.
More specifically to the mirrors there are areas that fall outside of their range to the right and left. When stationary these should be checked by looking round, and on the move should be checked with a sideways glance.
