Question

When you want to change lanes, you can see if another vehicle is in your blind spot:?

Answer 1

By looking over your shoulder. Looking out your mirrors, you may not see everything, so you must look over your shoulder.

Answer 2

huh?  How can you change lanes without seeing if someone's behind you?  Turn your head around for a split second.  

How about opening your window and peak out?  I also have special mini mirrors that point further out to the sides of the car.  Would htat be helpful for you?

Answer 3

You cannot see another vehicle in the blind spot on many vehicles....

Answer 4

You should adjust your mirrors, so that by checking your mirrors or turning your head, you have no blind spot.  There are little stick-on wide angle mirrors to eliminate blind spots.

Or you can get backup cameras.  They even have triple cameras for motorhomes, etc. that have a camera on each side and one behind.
