Environmental attorneys say a federal lawsuit filed Wednesday afternoon in U.S. District Court for the District of Connecticut against a well-known school bus company can have legs if the plaintiffs play their cards right.

Boston-based environmental nonprofit Conservation Law Foundation filed the suit after it said its investigators found drivers for New Britain-based DATTCO Inc. had left their buses idling for more than the three-minute maximum under state and federal law 132 times in October, November and earlier this month in numerous communities in Connecticut.
