A driver tells police someone came up behind them, flashed their headlights and then opened fire.
No one was seriously hurt but the victim's car was hit several times with bullets.
A baby was in the vehicle at the time.
This happened in the westbound lanes of the interstate near the Lake Station exit.
A young Merrillville couple was driving in their 2002 Chevy Cavalier westbound on Interstate 80/94 when the driver of a silver or gray Dodge Charger with dark tinted windows began flashing his headlights at them.
"He flashed his bright lights at them, they didn't move out of his way quickly enough, so just after a few seconds, he pulled alongside them and fired several rounds into the victim's vehicle," said Detective Mike Bailey, Indiana State Police. Bailey says the couple was on their way home after visiting family members to show them their 2-month-old baby boy.
The father was driving and the infant was in the back seat with his mother at the time of the shooting.
Bailey says it is a miracle the couple and baby survived the approximately seven rounds of bullets.
"As the shots started firing, the female kind of took cover leaning over the child, shielding the child. The rounds struck on the outside of her door," Bailey said. "Luckily they did not penetrate through and had they penetrated through, it woulld have had a homicide."
"Several rounds went through the glass passing through the vehicle and exiting the other window glass. We have a couple of rounds that missed the baby by mere inches," Bailey said.
Bailey says the couple is well-balanced and is helping police.
"The injuries were reported would have been superficial due to the breaking glass. It was a miracle no one was injured," Bailey says.
Indiana state police have released a sketch of the alleged offender.
Police say they are confident they will solve this case soon. The couple are very young and were too traumatize to talk with ABC7 on camera.
Indiana State Police are asking for anyone who may of witnessed the incident to please call 219-696-6242.
Police believe this was an isolated incident and a clear example of road rage.
