Camera systems are much better at revealing objects you could not otherwise see through the windows and mirrors.Īftermarket sensor and camera systems allow any vehicle to be retrofitted with some sort of warning device.Īftermarket backup cameras have adopted various designs. When you shift into reverse, the screen shows a wide-angle or fish-eye view to the rear. Other vehicles have backup cameras incorporated into their ($2,000 to $3,000) navigation system and some appear in the rear-view mirror. The sensor systems might work well as parking aids but they aren't informative enough to tip you to the presence of someone, particularly a small child. Many new cars have proximity sensors that beep with increasing frequency when you back toward solid objects. And that zone to the rear is bigger than you might think, ranging from about 25 feet for a minivan to 50 feet for some pickup trucks-plenty of space for an unwary child to be in harm's way. The main reason that back-over accidents are so frequent is that every vehicle has a rear blind zone-the area you can't see from the driver's seat. ![]() For the most part, back-over incidents take place in residential driveways or parking lots and about three-quarters of the time it is a parent or close relative who's behind the wheel. The safety advocacy group Kids and cars calculates that two children are killed and 48 are seriously injured this way every week in the United States. Every year, thousands of children are hurt or killed because a driver backing up didn't see them.
