The blind spots behind SUVs, minivans and other large vehicles are bigger than you might suspect. They can be as large as 70 feet. Often you don't know if an object or small child is hiding behind it. Many high-end cars now have cameras to help the driver with this, but motorists with other cars can purchase one, like the Audiovox DIY Collision Avoidance System.
It mounts to your license plate and you simply plug the monitor into your power outlet. It retails for $130.
"This system is fairly easy to install," said Todd Kent of Good Housekeeping Research Institute.
"You want the widest viewing angle possible, so it shows you what's behind your car to the left and to the right. And you want a clear image and you want a camera that delivers both a good picture in high light and low light," said Tom Malone, president of Audiovox Electronics.
Backup warning systems already built into a vehicle can be pricey.
The safest way to back up a vehicle is to turn around and look out your rear window. Don't just rely on mirrors.
