Citywide Council on Special Education Co-Chair Gloria Corsino said she was flooded with calls from parents whose kids with disabilities suffered on buses that were stuck on the roads for hours.

“These drivers don’t allow kids to eat on the bus or use the bathroom,” Corsino said. “Imagine the trauma. This is just poor emergency management.”

Manhattan City Councilman Ben Kallos said the storm exposed serious weaknesses in the city’s beleaguered, $1.2 billion yellow bus system, which is already undergoing an overhaul amid widespread service problems, allegations of corruption and a federal investigation.

“All of this could have been prevented,” said Kallos, a Democrat who represents the Upper East Side and intervened with the NYPD to help other kids with disabilities get home from the same stricken bus as Reynoso’s son.

“When you already have a bus route that’s three hours long, and then there’s a storm, it’s going to double or triple,” Kallos said. “We’re setting up these drivers and kids for failure.”

The city will investigate busing problems encountered in the storm, said Mayor de Blasio spokeswoman Jaclyn Rothenberg.
