SPRINGFIELD, Ill. – Gov. Rod Blagojevich is giving you one last chance.

If you owe the Illinois Tollway unpaid tolls, you have 60 days, starting Tuesday, to pay up.

Blagojevich signed into law Monday the two-month amnesty that if drivers disregard, they could face higher fines, lose their driver’s license or have their car impounded.

The law allows violators to pay only a portion of the tolls they owe. Those with up to 25 violations must pay 50 percent of the owed tolls, while those with up to 50 violations must pay 60 percent. If drivers have more than 50 violations, they have to pay 75 percent.

They still must pay the $20-per-violation fine, however.

Tollway officials estimate 106,000 people owe back tolls and are eligible for the amnesty program, spokeswoman Joelle McGinnis said. More than 90 percent of them owe between $100 and $500. The amounts are low enough that there’s a higher probably of collection, she said.

The legislation Blagojevich signed also expands employee ethics guidelines, enhances ongoing enforcement of tollway violations, and aims to improve tollway business practices to make them more efficient, open to the public, and service-oriented.

“The Illinois Tollway has made significant strides over the past two-and-a-half years to win back the confidence of Illinois’ drivers by proving that toll money is well spent and the Illinois Tollway is accountable to its customers,” Blagojevich said in a prepared statement.

The law amends the Toll Highway Act to require that the tollway give priority to maintaining its 274-mile network of roads and that money be spent only on tollway-related expenses. It puts into state law some practices already implemented, including annual public hearings and posting of documents on the tollway Web site.

It also formalizes in the Toll Highway law ethics guidelines that prohibit tollway officials from using their offices for personal gain.

People may pay back tolls and fines by going online at http://vpc.illinoistollway.com or calling, toll-free, 1-877-715-1235, from 7 a.m. to 7 p.m. Monday through Friday.

Personal checks are unacceptable, but cash will be accepted at tollway headquarters at 2700 Ogden Ave. in Downers Grove.

An electronic system to collect overdue tolls that started in January 2003 has brought in more than $43 million in back tolls and fines, McGinnis said.
