As per rules, a maximum of 12 children are allowed in these 8-seater vans.
The Delhi transport department on Tuesday issued notices to 12 schools after an NDTV report showed how private van operators were ferrying more than the permitted number of students and making them sit on top of the CNG cylinder.
The government will also form a monitoring team to ensure that illegal cabs do not ply on the streets of national capital
A joint meeting will also be held with the transport department, traffic police, schools and parents to resolve the issue.
As per rules, a maximum of 12 children are allowed in these eight-seater vans. Instead, 25 children were found stuffed in it.
According to government figures, a child died and over 70 were injured in school van accidents in the last three years.
Over two days, NDTV visited many schools to find the dangers our children face every day.
Outside one of south Delhi's private schools, the team spotted a school van. It had a private number and so was plying without a permit. Visibly scared of the camera, the driver bolted.
In another van, children were seen sitting on the top of the CNG cylinder - a highly dangerous situation.
"No, we don't make them sit on it," the driver insisted. "He is lying... We sit on it and often it even heats up," the children shouted back.
"Why have you stuffed so many children in a single van? It's an 8-seater van but you have 21 kids in it," we ask another cab driver. Caught off guard, he drives off, pushing away the mic.
Another private van was clearly very old - way beyond the permitted limit of 10 years for commercial vehicles.
According to a senior official, Delhi Transport Minister Gopal Rai has sought action against school-vans that are found violating the norms and called for an action taken report in this matter.
"We can go on impounding and challaning vehicles, but that doesn't solve the problem. The schools and parents need to come together for a holistic solution," said Mukhtesh Chandra, Special Commissioner of Police Traffic.
