NOTES: Passenger car occupants includes passenger car and light truck occupants. Air includes serious injuries only. Nonoccupant includes pedestrians and riders of nonmotorized bicycles and other pedal-powered vehicles. Total Highway, Passenger Car Occupants, and Motorcycle Operators: When comparing highway data from 2006 and before to data from later years, it needs to be understood that a revised methodology for estimating registered vehicles and vehicle miles traveled by vehicle type for the highway modes was applied to 2007 data and beyond, and this difference in methodologies needs to be taken into account.
