# What This Bill Does

Congress is trying to block new fuel efficiency rules that the National Highway Traffic Safety Administration (NHTSA) just created. These rules would require cars and light trucks made in 2027 and beyond to be more fuel efficient, and heavy-duty pickup trucks and vans made in 2030 and beyond to meet new efficiency standards as well. If this bill passes, those new rules would be canceled and wouldn't go into effect.

# Who This Affects and Why It Matters

This directly impacts car manufacturers, who would have to redesign vehicles to meet stricter fuel economy requirements if the rules stayed in place. For everyday drivers, the stakes are different depending on your perspective. If the rules go away, you might see cheaper vehicles in the short term since manufacturers won't need to invest as much in fuel-saving technology. However, you'd likely pay more at the gas pump over time since less efficient vehicles burn more fuel. On the flip side, if the rules stay, new cars would cost more upfront but save you money on gas over the vehicle's lifetime.

The bill also touches on a bigger debate about environmental policy and government regulation. Supporters of blocking the rule argue the government shouldn't impose such strict requirements on manufacturers. Opponents say these standards help reduce pollution and save consumers money on fuel in the long run. This is a straightforward congressional veto—if it passes both the House and Senate, the new fuel efficiency standards simply disappear and don't become law.

Providing for congressional disapproval under chapter 8 of title 5, United States Code, of the rule submitted by the National Highway Traffic Safety Administration relating to "Corporate Average Fuel Economy Standards for Passenger Cars and Light Trucks for Model Years 2027 and Beyond and Fuel Efficiency Standards for Heavy-Duty Pickup Trucks and Vans for Model Years 2030 and Beyond".
