The Department of Transportation said Tuesday that it will weigh freezing vehicle fuel economy standards at their current level and not raise them for model year 2022-2025 cars and trucks.

“A ‘no action’ alternative” will be considered as the agency puts together its environmental impact analysis for the new model-year rules beginning in 2022, according to a notice issued by the department’s National Highway Traffic and Safety Administration that is charged under a 40-year-old law with updating the standards.
