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.
Affected tractors are equipped with an automated Eaton UltraShift Plus or Eaton Advantage Transmission with right hand stalk shifter. In the affected trucks, the display on the instrument panel can indicate “N” when the shifter is set into “D” or “R,” causing the truck not to move.
