According to News8000, seven school buses were taken off the road in Minnesota last week after a safety feature was discovered missing.

The Minnesota State Patrol received an anonymous tip, which turned out be legitimate when police discovered several buses had a brake sensor removed.

The bus company Minnesota City Bus Service drives around 3,000 kids to schools every day.

State Patrol said the tip received highlighted multiple safety concerns and several equipment issues. They believe the missing brake sensor was the most important.

“The sensor was a little device that if the brake pressure or hydraulic pressure got low or wasn’t there that it would keep that idiot light on on the dashboard, that red light would stay on,” said Scott Hannon, superintendent of Winona Area Public Schools.

Coincidentally enough, the exact same thing happened nine years ago when a worker discovered an issue with a brake sensor underneath a few school buses at Minnesota City Bus Service headquarters.

The Minnesota City Bus Service is owned by a larger company Durham School Services. They released this statement to the public stating:

“Durham School Services’ top priority is safety; we are currently looking into the results of the recent fleet inspection which placed seven buses out of service due to a missing brake monitor module. Our first priority has been replacing the module to get the buses put back into service; we have successfully reinstated five of the seven buses.“
