Two people suffered serious injuries when a school bus smashed into a fence in Brooklyn on Wednesday morning. 

The victims, an 8-year-old boy and his 43-year-old mother, were rushed to Maimonides Medical Center with serious injuries, but are expected to be fine. 

The crash happened just before 8:30 a.m. at Bedford Avenue and Farragut Road in Ditmas Park, just feet away from the Cortelyou Early Childhood Center.

No students were on the bus at the time of the accident and the 66-year-old driver stayed at the scene. The bus is operated by Total Transportation Corporation. CBS News New York has reached out to the company but did not immediately hear back.

"It appeared the driver was driving and hit the gas instead of the brakes, trying to avoid another car, and that's how he crashed," City Councilmember Farrah Louis said. "We're glad this isn't a fatality. We do know we need more traffic safety in this area."

Video from the scene showed the bus partially on the sidewalk, with the front smashed through an iron fence and a cinderblock wall and poking into a neighboring building's driveway.

Witness Sandra Noel said she saw the bus along Farragut Road attempting to turn down Bedford Avenue right before the crash happened.

"The bus was waiting because a pedestrian was in front of the school bus and all of a sudden we heard a boom. [The bus] jumped over the pavement and crashed," Noel said.

A school employee said she heard a rumbling while she was inside.

"When the rumbling happened, I decided to look out the window and that's when I noticed the bus had actually come through the fence," the employee said.

The boy, a third-grader at the school, suffered a broken arm, and his mother suffered head and neck injuries, school employees said.

"Thank God they were conscious. She was able to speak to me. The little boy was pretty much in shock," the employee said.
