The drivers found out about the fines in August, when the Illinois Tollway mailed 85,000 bills to Indiana. Some face booth-skipping fines from as far back as 2008. They weren't notified earlier because the tollway's notification system was mistakenly left shut off.
The amount due was more like $7 million -- but the amount received is more than officials expected, according to the Tribune.
One woman from Lisle owed the state $50,000 back in 2009, when more than a million people were affected by a notification lapse. Tracy Patterson said tollway authorities made changes to her I-Pass account without telling her.
But officials created a ticket amnesty program for qualifying drivers that year -- Patterson settled her bill by paying a $612 fine.
