Phoenix ? Three models of small hybrid cars will be permitted to use car pool lanes on area freeways under an experiment that also will ban some alternative-fuel vehicles that currently use the special lanes.

The federally authorized pilot project was announced Friday by Gov. Janet Napolitano’s office. It will permit the Honda Insight, Honda Civic Hybrid and Toyota Prius to use the 73 miles of high-occupancy vehicle lanes if owners get required new plates and special permits. Hybrid vehicles run on either gasoline or self-generated electricity.

The state plans to issue 10,000 of the hybrid-vehicle permits on a first-come first-serve basis. There are 9,000 of those models registered in Arizona, officials said.

While hybrids are in, bi-fuel vehicles are out, under the program. Bi-fuel vehicles typically use gasoline but also are equipped to use an alternative fuel such as compressed natural gas.
