This will be the rule’s final version.
A proposed rule was published in 2012. The rule will take effect two years following its publication in the Federal Register.
NHTSA projects the rule will cost about $113 million per 150,000 trucks produced — based on 2012 figures.
“Rollover and loss-of-control crashes involving heavy vehicles is a serious safety issue that is responsible for 304 fatalities and 2,738 injuries annually,” NHTSA says in its rule synopsis. “They are also a major cause of traffic tie-ups, resulting in millions of dollars of lost productivity, and excess energy consumption each year.”
