Electronic stability control proposed for big rigs

The National Highway Traffic Safety Administration may soon require big rigs and other large trucks to have electronic stability control systems.

The technology could prevent a lot of accidents and rollovers. 

NHTSA already requires electronic stability control systems on passenger cars. The systems are able to automatically apply the brake on individual wheels. 

It's estimated electronic stability control reduces accidents where the driver loses control of the car by at least 40%.  There could be a similar benefit for big rigs, busses and other large trucks.

Russ Rader is with the Insurance Institute for Highway Safety.

"The technology is available, it's not expensive, and we should get it on large trucks."

NHTSA says a rule could become final within two to four years. 

The University of Michigan Transportation Research Institute estimates at least 4,600 truck accidents could be prevented if electronic stability control were required, and at least 126 lives saved per year.
