A blind spot is an area around the vehicle that cannot be directly observed by the driver while at the controls.
Blind spots exist on the rear and both sides of the car. There are also front blind spots created by the windscreen pillars.
Side blind spots are not eliminated by mirrors! Outside mirrors move the blind spot further from the side of the vehicle.
The sure and safe way to eliminate blind spots is to turn your head and look.
When driving, rear blind spots are checked by a quick glance over the shoulder.
You can work out the blind spots in your car by driving very slowly beside a parked vehicle and seeing the difference between mirror vision and reality.
