The federal government last week proposed a new motor vehicle safety standard to require electronic stability control (ESC) systems on large commercial trucks, motorcoaches and some other large buses — but not school buses.
ESC systems have sensors that monitor vehicle movement and steering. They can help mitigate rollover incidents by using automatic computer-controlled braking, and they can aid the driver in addressing severe understeer or oversteer conditions that can lead to loss of control.
NHTSA has proposed to require electronic stability control systems — which target rollovers — on large commercial trucks, motorcoaches and some other large buses, but not school or transit buses.
“We’ve already seen how effective stability control can be at reducing rollovers in passenger vehicles — the ability for this type of technology to save lives is one reason it is required on cars and light-duty trucks beginning with model year 2012,” NHTSA Administrator David Strickland said. “Now, we’re expanding our efforts to require stability enhancing technology on the many large trucks, motorcoaches and other large buses on our roadways.”
