Who’s “them” and what is “the test”?
You needed a licence to drive a bicycle?
School.
Hand signals.

Schools are in loco parentis , and designate how to handle things mime these.
With a term like that, it’s not weird to link Wikipedia, but I actually would’ve understood it without it as well.
But here in Finland schools aren’t in loco parentis for the trip to and from school. Only while school’s in. That’s why for instance schools here couldn’t sanction pupils for fighting on the way home.
