The two 15-year-olds, identified as Mary Elizabeth O'Reilly-Gindhart and Kelson D'Ambra, both students at Radnor High School, were hit around 7:00 a.m. in the 600 block of Conestoga Road.
The victims live across the street from each other and were waiting in a driveway for the school bus.
Instead, they found themselves in the path of an out of control Nissan Sentra.
The Nissan went up onto a porch and knocked over a support beam.
"I was sleeping in that bedroom. It was a big thud," said neighbor Tom Dreessen.
Neighbors say Dambra was unconscious after the crash. Both teens were airlifted to Children's Hospital of Philadelphia.
The 15-year-old boy was transferred to the Hospital of the University of Pennsylvania for surgery on both his head and leg. He is in critical condition.
The 15-year-old girl was last reported to be in serious condition at CHOP. She suffered cuts, bumps and bruises but did not suffer any broken bones or internal injuries. Police say she is expected to be released from the hospital on Tuesday morning.
Witnesses say four people were inside the car and were heading to work. The driver and the passengers were taken by ambulance to Bryn Mawr Hospital with non-life-threatening injuries.
Those witnesses also say the driver kept saying how sorry she was.
Meanwhile, police spent hours on the scene trying to piece together what led to the crash. The did not believe ice was a factor in this crash.
There is a bend in the road in that area, and nearby residents call it a danger zone.
Neighbor Todd Pitock said there have been a number of accidents there in the past.
"Cars are coming down at quite a rate of speed," he said. "They have to negotiate the turn and it bends hard to the right."
"The cars come down quickly," Pitock added, "and there have been incidents over the years."
Some questioned whether it was a safe place for the students to be waiting for a bus.
"I've worried about that before because I've seen the bus pull right up and it doesn't have any place to go. Even then they are blocking the road," said neighbor Bruce Colburn.
The family next door to where the crash happened actually placed boulders in front of their home to act as a buffer.
A district spokesperson declined an on camera interview. He says the district is praying for the two victims and it will investigate the safety of the bus stop.
