Some years ago I was on Test Track and a young kid got on next to me, I think it was questionable he was old enough to be riding alone and I think the CMs thought he was with me, but, I realised he didn't have his seat belt on as we got to the CM telling us to pull on the yellow tag, the boy didn't understand English and didn't listen to me telling him to put his seat belt on, the CM was going through the motions so didn't notice so I had to shout to him that the boy didn't have a seat belt on, so they held the ride long enough for me to sort it out, but, if he'd been on his own then who knows what may have happened.
