Teen-age drivers all over the United States are now facing a new test by being constantly watched. An array of new “black box” devices for cars is on the market, all in an effort to make roads safer and teen-agers better drivers.

According to the Insurance Institute for Highway Safety (IIHS) and the Highway Loss Data Institute, teen drivers have the highest crash risk of any age group, and 16-year-olds are the worst.

According to findings from the groups, crashes involving 16-year-olds involve driver error more often than crashes involving any other age group. To address these statistics, a few companies are selling products they hope will help teen-ager drivers and the public at large.
