Our district requires all parents and faculty who will drive students to a school approved event be "cleared" (TB test, background check...).
Anyone driving a vehicle that can hold 15 passengers needs a Commercial Drivers License.
Since the district makes groups pay for bus use we have parents with SUVs get cleared by the school and load the kids in. Not the best policy from an insurance point of view, but most of the parents know all the kids.
