Are they worried for his safety the rest of the day?

Obviously if this was a story about shared transport like a mini-bus or coach with other children this would be a sensible and sane decision. But it isn't, it is about the lad's mother, trained in the use of his drugs trying to make things safer for him by travelling with him.

This needs to be added to the list of things where some common sense is applied as Tom Mullarkey of RoSPA suggested last year while criticising the Health and safety “extremists”.
