The Diesel Engine Flexibility Act establishes a ten-year regulatory stability period for diesel engines used in on-road vehicles, non-road equipment, and heavy-duty trucks. During this time, the Environmental Protection Agency is prohibited from issuing new or stricter emission standards beyond the 2007 and 2010 rules for on-road vehicles, or the Tier 4 rules for non-road engines, unless specific exceptions for repairs or fraud enforcement apply. After the decade concludes, any new regulations must include a five-year delay before taking effect and must consider the financial and operational impacts on vehicle owners and manufacturers. The bill also provides legal protection for manufacturers using specific guidance documents to manage engine performance and monitor fluid quality without facing penalties.
The Protecting America from Chinese Cars Act of 2026 prohibits connected vehicles from entering the United States if they originate from or are designed in China, North Korea, Russia, or Iran, or if they are manufactured by companies with significant foreign ownership from those nations. This ban applies to vehicles equipped with internet connectivity used on public roads but includes an exception for those intended solely for testing and evaluation by U.S.-based entities with no foreign ties. The law allows the Commissioner of U.S. Customs and Border Protection to issue specific or general authorizations for vehicles that pass a security risk assessment proving they do not threaten national security or data integrity. These authorizations require a 60-day congressional review period and must be publicly listed, while the ban takes effect only after relevant regulations are published.
The Protecting America from Chinese Cars Act of 2026 prohibits connected vehicles from entering the United States if they are made in or designed within North Korea, China, Russia, or Iran, or if foreign entities from these countries control more than 15 percent of the manufacturer. This ban covers cars that use wireless technology to connect with networks or devices but allows exceptions for vehicles not meant for public roads or those brought in solely for testing by U.S.-based companies with no foreign ownership ties. The law also gives the Commissioner of U.S. Customs and Border Protection the power to issue special permits for specific vehicles after a detailed security review and a 60-day congressional review period. Once regulations are published, the ban will apply to any connected vehicle attempting to enter the country on or after that date.
The Connected Vehicle Security Act of 2026 restricts the importation, sale, and use of connected vehicles and related technology from China, Russia, Iran, and North Korea to protect national security. Starting in 2027, the bill generally bans these vehicles if they originate from or are controlled by these countries, with separate restrictions on software and hardware taking effect in 2030. The Secretary of Commerce is authorized to issue specific exemptions for items that do not pose a security risk and must publish a list of approved products. The law also requires companies to submit declarations confirming their vehicles comply with the rules and imposes heavy fines for violations.
This bill, titled the Stop Subsidizing Private Jets of 2026, prevents taxpayers from deducting expenses related to private fixed-wing aircraft on their federal income tax returns. It directly affects individuals and businesses that purchase, maintain, or operate personal planes, effectively removing the tax benefit previously available for these costs. The law allows deductions only for specific exceptions, such as aircraft used for property transport, agriculture, firefighting, emergency medical services, or commercial activities like flight instruction and sightseeing tours. These changes will apply to any expenses incurred after December 31, 2025.
The Connected Vehicle Security Act of 2026 restricts the importation, sale, and manufacture of vehicles and related technology from specific countries, including China, Russia, Iran, and North Korea, to address national security concerns. The law defines prohibited items as connected vehicles, their software, and hardware components and sets different effective dates, with vehicle bans starting in 2027 and hardware restrictions beginning in 2030. A government official can grant exceptions for specific items after reviewing security risks and notifying Congress, while the agency must publish annual reports on enforcement actions and compliance.
The Keeping China Off the Rails Act requires railroad freight cars placed into service in the United States to meet specific production age requirements that gradually increase over time. The bill directly affects railroad companies and freight car manufacturers by establishing a timeline where cars must be produced within progressively longer lookback periods, starting with cars made in the two years before enactment and eventually requiring all cars to meet the standard after four years. This phased approach aims to reduce the use of older freight cars that may have been manufactured in China by ensuring newer, domestically produced alternatives are used. The legislation does not ban Chinese-made cars outright but instead creates a schedule that limits their use as the required production window expands.
HR 2165, the Choice in Automobile Retail Sales Act of 2025, amends the Clean Air Act to prevent the Environmental Protection Agency (EPA) from writing future tailpipe emissions regulations that mandate specific vehicle technologies (like electric or hydrogen systems) or limit the availability of new vehicles based on engine type (e.g., gasoline vs. electric). The bill requires the EPA to update its regulations within 24 months to ensure new rules comply with these restrictions. This directly affects the EPA’s regulatory authority and automakers, as it limits how emissions standards can be structured. The law aims to preserve consumer choice in vehicle types by preventing regulations from favoring one engine technology over others.
This bill codifies existing protections for designated roadless areas within the National Forest System by prohibiting new road construction, road reconstruction, and logging in these areas. It directly affects National Forest lands already identified as "inventoried roadless areas" under the current Roadless Rule, which covers roughly 58 million acres. The key mechanism requires the Secretary of Agriculture to enforce these prohibitions, maintaining current protections without expanding restrictions to other lands or altering existing multiple-use management. The bill does not create new protected areas but legally solidifies the existing regulatory framework to preserve ecological and recreational values.
The STOP China Act prohibits federal funding for the procurement of certain vehicles (including buses) or related infrastructure from companies tied to China. It bans U.S. government contracts using "covered funding" for vehicles made by "covered entities" - defined as companies headquartered in China, controlled by China, or linked to Chinese state-owned entities, particularly those producing electric powertrains. The U.S. Trade Representative must publish and update a public list of these prohibited companies within 30 days of enactment, with quarterly updates initially. Exceptions allow funding for vehicle safety testing, investigations, and research, but the law directly affects federal transportation agencies, contractors, and companies with significant Chinese ownership or control.
