Proposed rule would mandate stability system

For the Record


The DOT’s National Highway Traffic Safety Administration announced in May a proposed federal motor vehicle safety standard to require electronic stability control systems on large commercial trucks, motor-coaches and other large buses.

Agency research shows the technology could prevent up to 56 percent of rollover crashes each year and another 14 percent of loss-of-control crashes.

While many truck-tractors and large buses can currently be ordered with this technology, the proposed standard would require ESC systems as standard equipment on these types of vehicles. As proposed, the rule would take effect between two and four years after the standard is finalized.
