OAK PARK, Ill. (CBS) — A teenage driver was killed in a crash early Friday on the Eisenhower Expressway, near the border between Chicago and Oak Park.

The single-vehicle rollover crash happened just before 4 a.m. on the outbound Eisenhower just west of Austin Boulevard, Illinois State Police said.

Atef Naser, 18, of Bridgeveiw, was heading west on the Eisenhower when he lost control and the 2003 ML 350 hit the left median wall and flipped, according to Illinois State Police District Chicago Master Sgt. Mike Witt.

Naser, 18, of Bridgeview, was ejected and dead on the scene, according to Witt. The Cook County Medical Examiner’s office was notified of the death, but had no further details immediately.

“Unfortunately, he was not wearing a seatbelt,’’ said Witt.

Speed may have played a factor in the wreck and no one else was inside the car, said Witt.

All outbound lanes were blocked for hours after the accident as crews investigated, but inbound lanes remained open. Outbound traffic was diverted off the expressway at Central Avenue.

CBS 2’s Kris Habermehl reports by 6 a.m., the right shoulder was back open. But the expressway was backed up solid all the way to Independence Boulevard.

This is the second fatal crash during the morning rush on an area expressway in as many days. Early on Thursday morning, Giuseppe Lasorella, 29, of Palos Hills, was killed when he car slammed into a five-axle dump truck on the inbound Stevenson Expressway near Central Avenue.
