The Ames Police Department is part of a law enforcement industry shift in vehicle use. Cmdr. Geoff Huff says the department is replacing its fleet of sedans with sport utility vehicles. He says car makers are offering smaller cars that make it difficult for officers to store and access equipment. Huff says the suvs get similar gas milage to the sedans currently in the fleet, which means department won't pay more for gas. He says the SUVs are also more visible in traffic and are better for getting around in snow. Huff says the sedans are being replaced after about two years and 100,000 to 130,000 miles.
