Chase Thompson is now breathing on his own and stable, his father said on Sunday.
The 12-year-old who has special needs was hit more than a week ago while crossing the street at night.
Chase's father said his prognosis is good, but he has "a long road to recovery."
"We cannot thank you all enough for your help in catching the driver, as well as for all the amazing support we have received," Thad Thompson said.
Chase suffered broken bones, injuries to his lungs and facial trauma, his family said.
