Trump administration moves to relax fuel efficiency standards for commercial trucks

The Trump administration has taken a step to ease fuel efficiency regulations for commercial trucks, rolling back Obama-era standards it claims go beyond federal authority. The new stance argues that only engine efficiency should be regulated, not the entire vehicle. This move is part of a broader push to deregulate environmental and safety rules that critics say could lead to higher emissions and less fuel economy, impacting everything from transportation costs to climate change efforts. This shift highlights ongoing tensions between regulatory rollbacks and environmental protection.
