A proposed rule by the Department of Transportation (DOT) could mandate rear-facing cameras in all new vehicles built after 2014.

CBS News reports that the DOT is mulling over the proposal, which was prompted by a 2007 piece of legislation in Congress known as the Cameron Gulbransen Kids Transportation Safety Act. Gulbransen was a two-year old child who was killed when his father backed over him while pulling out of the driveway, unable to see him because of a lack of visibility.

The National Highway Traffic Safety Administration estimates an average of 18,000 injuries and 292 fatalities every year that could be prevented with the new technology.

"There is no more tragic accident than for a parent or caregiver to back out of a garage or driveway and kill or injure an undetected child playing behind the vehicle," Transportation Secretary Ray LaHood said in a statement. "The changes we are proposing today will help drivers see into those blind zones directly behind vehicles to make sure it is safe to back up."

Rear-facing cameras are a recent technology and can be a bit expensive when equipped in a brand-new vehicle. Those who want to save a bit of cash may want to search for a late-model used vehicle that includes the feature.
