34-year-old Tamisha Johnson of Philadelphia is charged with reckless driving and reckless endangerment after the teens were hit by an out-of-control Nissan in late October.
Police released pictures of the tires on the car. The tread appeared to be missing from most of the tires and the metal wires beneath the rubber were exposed.
Investigators went on to say that Johnson had recently purchased the car with a valid inspection sticker, but that sticker was issued for another car. An investigation continues into how that happened.
Still, Radnor Police Superintendent Bill Colarulo said Johnson is responsible for the condition of her vehicle.
"It's unconscionable and inexcusable that anyone would operate a vehicle anywhere - whether it be Radnor Township or anywhere in the United States - in that kind of condition," Colarulo said. "It's inexcusable."
The crash happened around 7:00 a.m on October 31st in the 600 block of Conestoga Road.
Two 15-year-olds, identified as Mary Elizabeth O'Reilly-Gindhart and Kelson D'Ambra, both students at Radnor High School, were hit as they waited in a driveway for the school bus.
Police say it was not raining and there was no debris on the road at the time of the crash.
D'Ambra had to undergo surgery on both his head and leg and remains hospitalized but is said to be improving. O'Reilly-Gindhart suffered cuts, bumps and bruises but did not suffer any broken bones or internal injuries.
Witnesses say four people were inside the car and were heading to work. All were taken by ambulance to Bryn Mawr Hospital with non-life-threatening injuries.
Those witnesses also told Action News at the time that the driver, now identified as Johnson, kept saying how sorry she was.
