KNOX COUNTY, Tenn. (WVLT) - Parents of Karn kids who rely on bus 253 to get to school have complained for two years about overcrowding.

"It's dangerous, unpleasant, they don't like it. Especially my youngest one. She cries when she has to go on the bus. It's crowded. It's just an unpleasant situation," said Colleen Warren.

Warren's two daughters take the bus when she can't drive them herself. She says her oldest came home with a bruise after falling on the bus last year.

"I would call the transportation department and they would usually give me the response of, 'we'll get it fixed in a week. we'll get it fixed in a week.' It was always a week, and it was never fixed," said Warren.

The district insists those buses are equipped to carry 90 students, but parents say the current conditions with only 70 is dangerous.

"We can't afford having kids standing up in the seats. If the bus stops quickly, someone's going to fall. It's happened before. It's like a domino effect," said Warren.

After Local 8 News contacted the district about this story, it responded saying changes would be made starting tomorrow morning.

"While the bus has a capacity to carry 90 students, we understand the parents’ concerns, and two of the stops previously served by bus 253 will now be served by bus 87 (Beaver Creek Estates at Oak Ridge Highway and Beaver Ridge at Shady Oak Lane). This will result in a reduction of 34 eligible riders from bus 253. The school has been notified of this change and, in turn, the school will notify students this afternoon. This change is effective tomorrow morning," said Knox County Schools spokeswoman Melissa Copelan.
