WASHINGTON, D.C. — New recommendations from the National Transportation Safety Board (NTSB) call for stability control systems to be required on new commercial vehicles over 10,000 pounds.

In the recommendations — which includes school buses — the NTSB also calls on the National Highway Traffic Safety Administration (NHTSA) to develop stability control system performance standards for all commercial motor vehicles and buses with a gross vehicle weight rating above 10,000 pounds, regardless of whether they are equipped with a hydraulic or a pneumatic brake system.

The recommendations — which supersede earlier, similar recommendations (H-10-5 and H-10-6) — were among several from the NTSB in response to a 2009 incident in Indiana in which a tanker truck carrying liquefied petroleum gas rolled over and caught fire.
