Illinois Tollway glitch could give trucks cheaper rate

| Monday, July 18, 2005

The problematic Illinois Tollway has received a taste of its own medicine.

According to a new audit by the Illinois Auditor General, a flaw in the way the Tollway processes its pre-approved toll system – I-Pass – has the potential for charging tractor-trailers the same rate as four-wheelers.

Wow. What a shame.

According to the report, the Tollway – which recently expanded many of its I-Pass express lanes – didn’t install equipment on all of them that could count the number of axles on a vehicle. Because of this, all of the vehicle’s information was based on the I-Pass transponder inside the truck.

Under normal circumstances, this wouldn’t be a problem – unless, of course, the truck was carrying a passenger vehicle-designated transponder.

“A violation is only recorded in the lanes affected if there is no transponder to read or if a transponder read was identified as insufficient, invalid, lost or stolen,” said Auditor Jack Hartman in the report. “A violation would not be recorded if a vehicle passed through the lane with a transponder that does not correlate to the class of the vehicle.”

Without being able to differentiate between a Mack and a Mazda, unethical or unknowing truckers could simply purchase the wrong kind of transponder and slip through at a lower rate – 40 cents, compare to anywhere from $1 to $3.

Tollway officials did not announce how much lost revenue the glitch has caused, but did tell the Rockford Register Star that it should be eliminated by 2006.
