Have your mirrors correctly adjusted, if you can see your car in the mirror it is wrong. To correctly set the mirrors you will need to lean about 6in toward the mirror you are adjusting now angle the mirror to where you can just see the edge of the car, repeat on the other side. When done correctly it should eliminate most blind spots as a car behind you will move from the rear mirror to the side mirror with it being in both for just a second, when the car moves out of the view of the side mirror you should be able to the car because it is next to you.
