HELENA, Mont. (AP) — There are at least 64 Montana school bus drivers with criminal records, including two with drunken-driving convictions within the last three years, legislative auditors said Thursday.

In addition, some school districts appear to be taking advantage of a mileage reimbursement policy in which larger buses receive a higher rate, including one district that uses a 54-seat school bus to transport two students who live in the same house.
