A Good Samaritan saved lives and put his own life at risk when he stopped an impaired driver who nearly hit a construction crew on an Ohio highway.

Sean French, 39, said he saw a blue Ford speeding at about 80 miles an hour down the emergency lane when it hit the side wall as it passed him on Monday. He also noticed there was a child in the back seat.

He followed the car down Interstate 71 near Mason, in hopes of stopping the driver, 34-year-old Troy Morsch, who was later charged with driving while impaired.

Three miles up the road, French saw the driver pull into a grassy median. French stopped his car and jumped into the man's car to grab his keys in hopes of keeping him from re-entering the highway.

When French saw the car pull into a grassy median, he jumped out of his car and into the driver's window to put the car in park and remove the keys from the vehicle

The driver, later identified as 34-year-old Troy Morsch, failed a field sobriety test when police arrived on scene

'He stopped the car, I jumped out of my car, jumped into his car through the window, threw the car in park and grabbed the key out of the ignition,' French told WLWT.

'If this was my child that was in danger, I'd want somebody to get it, to step in to help my child whatever it took and I just did whatever it took,' he added.

French began filming the incident shortly after grabbing the keys from the man. Another person took Morsch's one-year-old daughter out of the back seat and watched her until police arrived.

In the footage he asks the man what he was doing, or if he was aware of what he had done.

At one point, French asks Morsch to unlock his phone so he can call his wife to tell her what happened, but Morsch seems unresponsive and would not unlock his phone for French.

'He was definitely not saying a whole lot, didn't realize what his surrounding was, didn't realize there was a baby in the car, he just had no clue what was going on,' French told WLWT.

While on his high-speed drive, Morsch nearly hit an ODOT work crew, according to the Ohio Sate Highway Patrol, WCPO reported.

Callers said he had a flat left front tire but continued to drive until he ended up in the grassy area where French stopped him.

'He swerved at the last minute. He missed them by inches,' French told WLW radio on Wednesday. 'They came up after he stopped and wanted to talk to him. They were kinda upset.'

Morsch failed a field sobriety test. His daughter was unharmed and released to her mother, the highway patrol report said.

He was arrested and charged with operating a motor vehicle while impaired, operating a motor vehicle without control and child endangering.

French said he would stop an impaired driver again if he needed to.

'The past two nights I laid in bed and thought, "Oh boy". I'm absolutely glad I did it because it turned out all right. But I realize there was a 99 percent chance it wouldn't,' he said.

The car was covered in dents by the time Morsch pulled off the highway. He was arrested and charged with operating a motor vehicle while impaired, operating a motor vehicle without control and child endangering
