Toll cheaters are becoming a big problem on Maryland's Intercounty Connector.
About one-third of ICC drivers who don't use an E-ZPass don't pay the toll later, according to a report in The Washington Post.
That's four times the state average.
Maryland is still trying to collect about $670,000 in unpaid tolls from just the first half of the year.
Thursday will mark one year since the Intercounty Connector first opened.
