1 The completeness of data on trailer registrations varies greatly among states. Data are reported to the extent available and, in some cases, are supplemented by Federal Highway Administration estimates.

2 This column includes all commercial type vehicles and semi-trailers that are in private or for-hire use.

3 Several states do not require the registration of light farm or automobile trailers.

4 Some states may not require the registrations of mobile homes and house trailers. In states where this classification is not available, house trailers are included with light car trailers.

KEY: U = data are unavailable.
