The Trump administration’s announced CAFE changes would replace older light-truck criteria with a towing-and-payload measure starting in model year 2030. The change could move some midsize crossovers from the light-truck category into the passenger-car category, even as emissions requirements for vehicles that remain light trucks are eased.
The Trump administration announced changes to Corporate Average Fuel Economy (CAFE) rules that would replace older light-truck classification criteria with a test based on towing and payload capacity, beginning with the 2030 model year. The change could classify some midsize crossovers as passenger vehicles, even as the administration eases emissions requirements for vehicles that still qualify as light trucks.
Under the existing framework, vehicles can qualify as light trucks through several pathways, including design features and measurements tied to off-road capability. The Drive reports that those criteria date to rules established in 1975 and were intended to account for vehicles used for work or other non-passenger purposes. The report says automakers have also used the criteria to qualify some vehicles for the less stringent standards applied to light trucks.
For model year 2030 and later, the new approach would use a measure NHTSA calls “Light Duty Work Factor” (LDWF), calculated by adding a vehicle’s towing and payload capacities. A vehicle would qualify as a non-passenger automobile, or light truck, if its LDWF is at least 8,500 pounds. Gross vehicle weight rating would be used to calculate payload; other size and off-road measurements would no longer determine the classification under this formula.
The Drive says large trucks and SUVs are expected to meet the threshold, while some midsize crossovers could fall below it and be treated as passenger vehicles. The report also says the rules would ease emissions requirements for light trucks, but that category would be narrower if more crossovers were classified as passenger vehicles.
How Crossover Classifications Could Shift
The classification matters because CAFE standards differ between passenger cars and light trucks. If a crossover that currently qualifies as a light truck is reclassified as a passenger vehicle, it would be assessed under the passenger-vehicle rules. The Drive says this could put additional pressure on manufacturers to improve the fuel economy of some crossovers, although the practical effect will depend on how the standards are enforced.
The change also complicates a simple reading of the broader rollback as a benefit for every large vehicle. While requirements would be eased for the light trucks that remain in that category, some vehicles could leave it. The report cautions that CAFE enforcement currently has limited force, so a change in classification does not by itself establish that manufacturers will make particular design or production decisions.

Why the 1975 Criteria Are Changing
The current light-truck framework was built around categories such as vehicles carrying more than 10 people, providing temporary living quarters, transporting property on an open bed, or having greater cargo than passenger volume. Another route combined four-wheel drive or a gross vehicle weight rating above 6,000 pounds with specified approach, breakover and departure angles and minimum running clearance.
NHTSA’s report says it excluded vehicles that qualify through these alternative pathways from an analysis of whether a vehicle was designed chiefly for property-transporting utility, because their designs may include other non-passenger or off-highway features. The agency says the proposed performance-based measure focuses on the ability to transport property through payload and towing capacity. The Drive notes that the approach angle and clearance figures resemble specifications used by off-road vehicles, which can make them relevant to automakers seeking light-truck classification.
Enforcement and Market Effects Remain Open
The available report does not quantify how many current or future crossovers would fall below the 8,500-pound LDWF threshold. It also does not establish how manufacturers would respond, or how much any reclassification would change fleet fuel economy in practice. The Drive says CAFE enforcement currently has limited force, but the source material does not detail what enforcement changes, if any, may follow.
The administration has announced the changes, but the supplied source does not provide a full implementation schedule beyond the planned 2030 model-year start. The eventual effects will depend on the final rule’s terms, agency implementation and enforcement.
The 2030 Model-Year Threshold
The announced classification test is slated to begin with vehicles from the 2030 model year. As the rule moves toward implementation, manufacturers and regulators will need to apply the towing-and-payload calculation to individual vehicles. That will show which crossovers remain light trucks and which are assessed as passenger vehicles.
Further details on enforcement and the effects on vehicle fuel economy will be needed to judge the rule’s real-world impact. Until those are available, the likely shift for midsize crossovers remains a consequence described by the source report, rather than a measured market outcome.
Key Questions
What is the proposed Light Duty Work Factor?
LDWF adds a light-duty vehicle’s towing and payload capacities to determine whether it qualifies as a light truck under the new approach.
What LDWF value qualifies a vehicle as a light truck?
Under the announced rules, a vehicle with an LDWF of 8,500 pounds or more would qualify as a non-passenger automobile, or light truck, starting with the 2030 model year.
Could the change affect midsize crossovers?
Yes. The Drive reports that some midsize crossovers may not meet the threshold and could be classified as passenger vehicles. The source does not identify how many models would be affected.
Will the rules change standards for all trucks and SUVs?
The announced changes would ease emissions requirements for vehicles that qualify as light trucks, while replacing the classification test. The report says large trucks and SUVs are expected to meet the new threshold; it does not provide a model-by-model assessment.
