Blind spots are areas that cannot be seen in the side and rearview mirrors of a vehicle. They are typically located slightly behind and to the side of the driver and can only be seen by physically turning your head to check over your shoulder. It's important to check these blind spots before changing lanes or making a turn to ensure there are no vehicles present.
When sitting in the driver's seat, the area on both sides of the vehicle from the back seat/door to almost the rear bumper can be "blind" spots. You must look back over your shoulder(s), check your rear view mirror, and side mirrors.
