In December 2016, pursuant to the Inflation Adjustment Act of 2015, the National Highway Traffic Safety Administration (NHTSA) finalized a rule that adjusted civil penalties for car manufacturers that violate fuel economy standards, in order to line them up better with inflation. That rule put the penalties at $14 per tenth of a mile per gallon. NHTSA is now proposing a new rule to lower the penalties from $14 per tenth of a mile per gallon back to the previous rate of $5.50 per tenth of a mile per gallon, claiming that the $14 penalty would have a significant negative economic impact.
Our May 2018 comments argue that NHTSA should explain why it is justified in reducing the penalty from $14 to $5.50 and consider the forgone benefits when considering whether the civil penalties will have a “negative economic impact.” Because NHTSA has not provided this explanation, the proposed reduction is arbitrary and capricious.
Read our amicus brief and expert affidavit in the suit against NHTSA over a delay of the 2016 penalties adjustment, a suit which resulted in a court vacating the delay.
