Backup cameras will be mandatory for automakers by May 2018. The NHTSA on Monday issue new regulation that requires all vehicles under 10,000 pounds be equipped with rear-visibility cameras. The regulation, clearly, is meant to encourage a safer environment for both pedestrians and drivers, ensuring folks are fully aware of their surroundings. Most cars today are already equipped with such technology, but the mandate ensures that automakers follow a universal policy for the benefit of safety.
