Liability in School setting

Hi!
I am on OT that works in a school in a school in NY. We service children with multiple disabilities and are interested in building some GBG cars to use in our therapy programs- and possibly expand from there. Our administration has some concerns about liability with the adaptive cars. Im wondering if anyone works in a school or hospital setting similar to our that uses these cars and can help us navigate how you handle liability with students.

Thanks!
