(Annapolis, MD) — A recent audit conducted by an arm of the Maryland General Assembly is showing that thousands of drivers were overcharged at state toll facilities. The review of data between April 2021 and January 2022 found the Maryland Transportation Authority collected more than a million bucks in potentially improper tolls from around 90-thousand customers. The MDTA provided a variety of reasons for the errors, but says all the accounts identified in the audit as having been overbilled have received refunds. Technical issues with electronic tolling were tied to many of the incorrect charges.
