An audit has revealed that the Maryland Transportation Authority (MDTA) failed to collect a staggering $818.1 million in tolls and penalties from out-of-state drivers. The findings highlight missed opportunities for pursuing this significant unpaid debt. The situation raises concerns about the efficiency of toll collection processes, as it was reported that hundreds of millions remain uncollected. The implications of this audit warrant further investigation into the methods used by the MDTA to manage toll collections and enforcement.
