CarFax reports are primarily designed for passenger vehicles, including cars, trucks, SUVs, and vans that are registered in the United States and Canada. However, the availability of reports for other types of vehicles, such as motorcycles, recreational vehicles, and commercial vehicles, may be limited. CarFax focuses on providing detailed history reports that include information like accident history, title status, service records, and odometer readings for the vehicles it covers. To determine whether a specific vehicle type has a report available, it is advisable to visit the CarFax website and enter the vehicle identification number, or VIN, to see if a report can be generated for that particular vehicle. This can provide the most accurate and up-to-date information regarding report availability.
