HOBE SOUND, Fla. — A driver and two passengers are recovering after an "unknown" object hit a truck on Interstate 95 Thursday night, knocking the driver unconscious.
The incident happened in the southbound lanes of I-95 at mile marker 94 in Hobe Sound at around 9 p.m.
Martin County Fire Rescue said in a Facebook post that an unknown object, possibly a tire, struck the truck, knocking the driver unconscious. A passenger had to take control of the wheel and pull the vehicle over.
There was a trailer on the northbound side of the road, just north of the scene, missing a wheel, but there was no vehicle and no witnesses to provide information, according to Martin County Fire Rescue.
The driver suffered serious injuries and all southbound lanes were closed for about 30 minutes as rescue crews airlifted the person to the hospital.
Two passengers were taken to the hospital with non-life threatening injuries.
Cory Pippin of Martin County Fire Rescue said the main thing is to be as cautious as possible in a situation like this.
"Unfortunately, there's not a whole lot you can do in regard to slowing down the vehicle. At that point, it's about trying to be as cautious as possible to make sure you're holding on to the wheel and not lose control," Pippin said. "Hopefully, at that point, the driver's foot will be off the gas and you can coast to a stop."
The cause of the crash is under investigation.
