What are the various vehicle weight classes and why do they matter?
How do I know which Corporate Average Fuel Economy (CAFE) standard applies to my vehicle? What are the state emissions testing requirements for my vehicle? Would a medium-duty vehicle qualify for the plug-in electric drive motor vehicle tax credit? To answer these questions, you must first understand the specifics of the vehicle weight classifications to determine which laws, regulations, and incentives may apply to your vehicle or fleet.
You may recall learning about federal agencies and vehicle classes from our February Question of the Month. However, each agency defines vehicle classes differently. So this month, we will dig deeper into the specific vehicle weight classes set by three federal agencies. This guide will help you identify a Class 1 vehicle to a Heavy-Duty Vehicle 8b, and everything in between.
U.S. Department of Transportation Federal Highway Administration (FHWA)
The FHWA defines vehicles as Class 1 through 8, the most common categorization used in the fleet industry.
