A Philadelphia judge has certified a class action in which the plaintiffs allege that AAA Mid-Atlantic breached its contracts with local tow truck companies providing emergency roadside services to AAA members by instead assigning emergency calls to AAA’s own fleet of tow trucks.

Philadelphia Court of Common Pleas Judge Patricia A. McInerney certified a class of tow truck contractors who entered roadside assistance service provider agreements with AAA Mid-Atlantic from 1990 through September 30, 2005, in an order issued Monday.
