The U.S. Supreme Court this week denied a request from a group of truckers to hear their appeal in a case over Indiana Toll Road rates.

The two-year-old lawsuit that sought to overturn a significant rate hike is now over.

The rate for “heavy” trucks – those with three or more axles – went up 35 percent in 2018 on the Indiana Toll Road, which spans the northernmost part of the state. Truck drivers sued, arguing the hike was unconstitutional because it interfered with interstate commerce.

But those truckers found no success in federal courts. Judges at each level sided with the state. In March, the 7th Circuit Court of Appeals ruled for Indiana, telling truckers they could always drive across the state on one of two, toll-free interstate highways that cross east to west.

The truckers asked the Supreme Court to take their appeal but the nation’s high court said no, without explanation.
